    Description / Table of Contents: Sn5Ir6B2 and Sn4Ir7B3: Tin Iridiumborides with Onedimensional Ir/B Structural ElementsSn5Ir6B2 (hexagonal, P62m, a = 658.97(5) pm, c = 559.19(3) pm, Z = 1, 391 reflexions, 16 parameters, R = 0.037) and Sn4Ir7B3 (hexagonal, P63/m, a = 926.63(5) pm, c = 563.19(3) pm, Z = 2, 323 reflexions, 24 parameters, R = 0.045) were prepared by reaction of the elements. Their structures were determined by means of single crystal X-ray methods.The structure of Sn5Ir6B2 may be derived from the Fe2P type and contains columns of boron centered trigonal Ir prisms sharing their triangular faces. In the structure of Sn4Ir7B3 six of these columns are connected to form a large column with hexagonal cross section. Only every second prism therein is occupied by a boron atom. In both structures these onedimensional Ir/B structural elements are embedded in a matrix of tin atoms composed of Sn-centered Sn6 prisms twice as long as the Ir6 prisms.
    Notes: Sn5Ir6B2 (hexagonal, P62m, a = 658,97(5)pm, c = 559,19(3) pm, Z = 1, 391 Reflexe, 16 Parameter, R = 0,037) und Sn4Ir7B3 (hexagonal, P63/m, a = 926,63(5) pm, c = 563,19(3) pm, Z = 2, 323 Reflexe, 24 Parameter, R = 0,045) wurden durch Umsetzung der Elemente dargestellt, Ihre Strukturen wurden mit Röntgeneinkristallmethoden bestimmt.Die Sn5Ir6B2-Struktur kann vom Fe2P-Typ abgeleitet werden. Sie enthält Säulen aus trigonalen Ir-Prismen, die über die Dreiecksflächen verknüpft und von Boratomen zentriert sind. In der Sn4Ir7B3-Struktur sind jeweils sechs solcher Säulen aus Ir-Prismen über die Seitenflächen zu einer Säule mit sechseckigem Querschnitt zusammengefaßt. Darin ist nur jedes zweite Prisma mit Bor besetzt. In beiden Strukturen sind diese eindimensionalen Ir/B-Verbände in eine Matrix aus Zinnatomen eingelagert, die aus Sn-zentrierten Sn6-Prismen von der doppelten Länge der Ir6-Prismen aufgebaut ist.

    Description / Table of Contents: The Tin Rhodium Borides SnRh3B1-x, Sn4Rh6B, and Sn5Rh6B2The new compounds SnRh3B1-x (x ∼ 0.2, tetragonal, P4/mbm, a = 570.31(2) pm, c = 835.99(8) pm, Z = 4, 514 reflexions, 26 parameters, R = 0.026), Sn4Rh6B (hexagonal, P63/mmc, a = 560.01(3) pm, c = 1367.5(1) pm, Z = 2, 746 reflexions, 17 parameters, R = 0.035), and Sn5Rh6B2 (hexagonal, P62m, a = 654.80(7) pm, c = 557.32(9) pm, Z = 1, 361 reflexions, 16 parameters, R = 0.039) were prepared by reaction of the elements. SnRh3B1-x crystallizes with the filled U3Si type of structure, a distortion variant of the cubic perovskite; the structure of Sn4Rh6B may be derived from the hexagonal perovskite BaNiO3. Both compounds contain nearly regular Rh6B-octahedra. Sn5Rh6B2 with the Sn5Ir6B2 type of structure contains isolated colums composed of trigonal Rh6B-prisms.
    Notes: Die neuen Verbindungen SnRh3B1-x (x ∼ 0,2, tetragonal, P4/mbm, a = 570,31(2) pm, c = 835,99(8) pm, Z = 4, 514 Reflexe, 26 Parameter, R = 0,026), Sn4Rh6B (hexagonal, P63/mmc, a = 560,01(3) pm, c = 1367,5(1) pm, Z = 2, 746 Reflexe, 17 Parameter, R = 0,035) und Sn5Rh6B2 (hexagonal, P62m, a = 654,80(7) pm, c = 557,32(9) pm, Z = 1, 361 Reflexe, 16 Parameter, R = 0,039) wurden durch Reaktion der Elemente dargestellt. SnRh3B1-x kristallisiert in einem aufgefüllten U3Si-Typ, einer verzerrten Variante des kubischen Perowskits; Sn4Rh6B läßt sich von der Struktur des hexagonalen Perowskits BaNiO3 ableiten. Beide Verbindungen enthalten nahezu reguläre Rh6B-Oktaeder. Sn5Rh6B2 ist isotyp mit Sn5Ir6B2 und enthält isolierte Säulen aus trigonalen Rh6B-Prismen.
