    Description / Table of Contents: Li3BS3 and LiSrBS3: New Orthothioborates with Trigonal Planar Boron CoordinationWe report on the two new orthothioborates Li3BS3 (Pnma; a = 8.144(1) Å, b = 10.063(2) Å, 6.161(1) Å; Z = 4) and LiSrBS3 (Pnma; a = 7.557(1) Å, b = 9.083(2) Å, c = 7.049(1) Å: Z = 4). The two new phases were prepared by reaction of the metal sulfides, amorphous boron, and sulfur at 700°C. Both compounds contain isolated, planar [BS3]3--anions. The lithium ions have fourfold (Li3BS3) and sixfold (LiSrBS3) sulfur coordination, the strontium ion shows an eightfold sulfur coordination. The two compounds represent new A3BX3 resp. AA′BX3 structure types.
    Notes: Es wird über die beiden Orthothioborate Li3BS3 (Pnma; a = 8,144(1) Å, b = 10,063(2) Å, 6,161(1) Å; Z = 4) und LiSrBS3 (Pnma; a = 7,557(1) Å, b = 9,083(2) Å, c = 7,049(1) Å; Z = 4) berichtet. Die beiden neuen Phasen wurden durch Hochtemperatur-Schmelzreaktion aus den Metallsulfiden, amorphem Bor und Schwefel bei 700°C dargestellt. Beide Verbindungen enthalten isolierte, planare [BS3]3--Anionen. Die Lithiumionen sind vierfach (Li3BS3) bzw. sechsfach (LiSrBS3) von Schwefel umgeben, das Strontiumion weist eine achtfache Schwefelkoordination auf. Li3BS3 und LiSrBS3 bilden neue A3BX3 bzw. AA′BX3-Strukturtypen.

    Description / Table of Contents: Li5B7S13 and Li9B19S33: Two Lithium Thioborates with Novel Highly Polymeric Anion NetworksLi5B7S13 (C2/c; a = 17.304(2) Å, b = 21.922(3) Å, c = 12.233(2) Å, β = 134.91(1)°; Z = 8) and Li9B19S33 (C2/c; a = 23.669(9) Å, b = 14.361(3) Å, c = 12.237(3) Å, β = 103.77(2)°; Z = 4) were prepared by reaction of stoichiometric amounts of lithium sulfide, boron, and sulfur at 750°C (Li5B7S13) and 700°C (Li9B19S33) with subsequent annealing. The crystal structures consist of interpenetrating, polymeric boron sulfur anion networks which are formed by corner-sharing of B4S10 and B10S20 units (Li5B7S13), or B19S36 units (Li9B19S33). The lithium cations are situated in between with a strong disorder in Li9B19S33.
    Notes: Li5B7S13 (C2/c; a = 17,304(2) Å, b = 21,922(3) Å, c = 12,233(2) Å, β = 134,91(1)°; Z = 8 und Li9B19S33 (C2/c; a = 23,669(9) Å, b = 14,361(3) Å, c = 12,237(3) Å, β = 103,77(2)°; Z = 4 wurden durch Reaktion von stöchiometrischen Mengen Lithiumsulfid, Bor und Schwefel bei 750°C (Li5B7S13) und 700°C (Li9B19S33) mit anschließendem Tempern dargestellt. Die Kristallstrukturen bestehen aus sich durchdringenden, polymeren Bor-Schwefel-Anionengerüsten, die durch Eckenverknüpfung von B4S10- und B10S20-Einheiten (Li5B7S13) bzw. B19S36-Einheiten (Li9B19S33) gebildet werden. Dazwischen befinden sich die Lithiumkationen, wobei bei Li9B19S33 eine starke Fehlordnung beobachtet wird.

    Description / Table of Contents: LiBaBS3 and LiBaB3S6: Two New Quaternary Thioborates with Trigonally Coordinated BoronLiBaBS3 (P21/c; a = 7.577(2) Å, b = 8.713(2) Å, c = 8.687(2) Å, β = 116.22(2)°; Z = 4) und LiBaB3S6 (Cc; a = 15.116(3) Å, b = 8.824(2) Å, c = 8.179(2) Å, β = 117.46(3)°; Z = 4) were prepared by reaction of stoichiometric amounts of the metal sulfides, boron, and sulfur at 750°C. The anionic part of the structure of the orthothioborate LiBaBS3 consists of isolated planar [BS3]3- anions. The crystal structure of the metathioborate LiBaB3S6 contains [B3S6]3- anions formed by six-membered B3S3 rings with three exocyclic sulfur atoms. The metal cations are situated between the anion units leading to a ninefold sulfur coordination of the barium atoms and to a fivefold (LiBaBS3) and fourfold (LiBaB3S6) coordination of the lithium atoms.
    Notes: LiBaBS3 (P21/c; a = 7,577(2) Å, b = 8,713(2) Å, c = 8,687(2) Å, β = 116,22(2)°; Z = 4) und LiBaB3S6 (Cc; a = 15,116(3) Å, b = 8,824(2) Å, c = 8,179(2) Å, β = 117,46(3)°; Z = 4) wurden durch Reaktion stöchiometrischer Mengen der Metallsulfide mit Bor und Schwefel bei 750°C dargestellt. Die Anionenteilstruktur des Orthothioborats LiBaBS3 besteht aus isolierten, planaren [BS3]3--Anionen. Die Kristallstruktur des Metathioborats LiBaB3S6 enthält [B3S6]3--Anionen aus B3S3-Sechsringen mit drei exocyclischen Schwefelatomen. Die Metallkationen befinden sich jeweils zwischen den Anioneneinheiten, wobei für Barium eine neunfache, für Lithium eine fünffache (LiBaBS3) bzw. vierfache (LiBaB3S6) Koordination durch Schwefel beobachtet wird.

    Description / Table of Contents: The Perthioborates RbBS3, TIBS3, and Tl3B3S10.RbBS3 (P21/c, a=7.082(2) Å, b=11.863(4) Å, c=5.794(2) Å, β=106.54(2)°) was prepared as colourless, plate-shaped crystals by reaction of stoichiometric amounts of rubidium sulfide, boron, and sulfur at 600°C and subsequent annealing. TlBS3 (P21/c, a=6.874(3) Å, b=11.739(3) Å, c=5.775(2) Å, β=113.08(2)°) which is isotypic with RbBS3 was synthesized from a sample of the composition Tl2S · 2 B2S3. The glassy product which was obtained after 7 h at 850°C was annealed in a two zone furnace for 400 h at 400→350°C. Yellow crystals of TlBS3 formed at the warmer side of the furnace.Tl3B3S10 (P1, a=6.828(2) Å, b=7.713(2) Å, c=13.769(5) Å, α=104.32(2)°, β=94.03(3)°, γ=94.69(2)°) was prepared as yellow plates from stoichiometric amounts of thallium sulfide, boron, and sulfur at 850°C and subsequent annealing.All compounds contain tetrahedrally coordinated boron. The crystal structures consist of polymeric anion chains. In the case of RbBS3 and TlBS3 nonplanar five-membered B2S3 rings are spirocyclically connected via the boron atoms. To obtain the anionic structure of Tl3B3S10 every third B2S3 ring of the polymeric chains of MBS3 is to be substituted by a six-membered B(S2)2B ring.
    Notes: Farblose, plättchenförmige Kristalle von RbBS3 (P21/c, a=7,082(2) Å, b=11,863(4) Å, c=5,794(2) Å, β=106,54(2)°) entstehen aus einem stöchiometrischen Ansatz von Rubidiumsulfid, Bor und Schwefel bei 600°C und anschließendem Tempern. Die zu RbBS3 isotype Phase TlBS3 (P21/c, a=6,874(3) Å, b=11,739(3) Å, c=5,775(2) Å, β=113,08(2)°) erhält man aus dem Ansatz Tl2S · 2 B2S3. Das nach 7 h bei 850°C erhaltene glasige Produkt wird in einem Zweizonenofen 400 h bei 400→350°C ausgelagert. Gelbe Kristalle der Verbindung bilden sich in der wärmeren Ofenzone. Das ebenfalls gelbe Tl3B3S10 (P1, a=6,828(2) Å, b=7,713(2) Å, c=13,769(5) Å, α=104,32(2)°, β=94,03(3)β, γ=94,69(2)°) bildet sich aus stöchiometrischen Mengen von Thalliumsulfid, Bor und Schwefel bei 850°C und anschließendem Tempern.Die ausschließlich tetraedrisch koordiniertes Bor enthaltenden Verbindungen bilden polymere Kettenstrukturen, die sich im Fall des RbBS3 und TlBS3 aus spirocyclisch über die Boratome verknüpften, nichtplanaren Trithiadiborolan-Ringen aufbauen. Ersetzt man in diesen Anionenketten jeden dritten B2S3-Fünfring durch einen B(S2)2B-Sechsring, so erhält man die Anionenstruktur des Tl3B3S10.

    Description / Table of Contents: Synthesis and Crystal Structures of Li4-2xSr2+xB10S19 (x ≈ 0.27) and Na6B10S18. Two Novel Thioborates with Highly Polymeric Macro-tetrahedral NetworksLi4-2xSr2+xB10S19 (x ≈ 0.27) and Na6B10S18 were prepared from the reaction of strontium sulfide and lithium sulfide (sodium sulfide) with boron and sulfur at 700°C in graphitized silica tubes. Li4-2xSr2+xB10S19 (x ≈ 0.27) crystallizes in the monoclinic space group P21/c with a = 10.919(2) Å, b = 13.590(3) Å, c = 16.423(4) Å, and β = 90.48(2)°, Na6B10S18 in the tetragonal space group I41/acd with a = 14.415(3) Å, c = 26.137(4) Å. Both structures contain supertetrahedral B10S20 units which are linked through tetrahedral corners to form a three-dimensional polymeric network in the case of Na6B10S18 and one-dimensional chains in the case of Li4-2xSr2+xB10S19 (x ≈ 0.27). All boron atoms are in tetrahedral BS4 coordination (B—S bond lengths vary from 1.879(5) to 1.951(5) Å (1.875(10) to 1.987(9) Å)). The strontium and lithium (sodium) cations are located within large channels formed by the anions.
    Notes: Li4-2xSr2+xB10S19 (x ≈ 0,27) und Na6B10S18 wurden aus der Summenformel entsprechenden Mengen Strontiumsulfid und Lithiumsulfid (Natriumsulfid), amorphem Bor und Schwefel bei 700°C in graphitierten Quarzglasampullen dargestellt. Li4-2xSr2+xB10S19 (x ≈ 0,27) kristallisiert monoklin in der Raumgruppe P21/c mit a = 10,919(2) Å, b = 13,590(3) Å, c = 16,423(4) Å, und β = 90,48(2)°, Na6B10S18 tetragonal in der Raumgruppe I41/acd mit a = 14,415(3) Å, c = 26,137(4) Å. Beide Strukturen enthalten supertetraedrische B10S20-Einheiten, die über Tetraederecken zu einem dreidimensionalen polymeren anionischen Raumnetzwerk im Falle des Na6B10S18 bzw. zu eindimensionalen Anionen-Ketten im Falle des Li4-2xSr2+xB10S19 (x ≈ 0,27) verbunden sind. Alle Boratome haben tetraedrische BS4-Koordination (die B—S-Abstände variieren von 1,879(5) Å bis 1,951(5) Å (1,875(10) Å bis 1,987(9) Å)). Die Strontium- und Lithium-(Natrium-)Kationen befinden sich in ausgedehnten Kanälen innerhalb des Anionengerüsts.
