    Description / Table of Contents: Polysulfonyl Amines. LXIX. Novel Pnictogen Disulfonylamides: Synthesis of Bismuth Dimesylamides and Crystal Structures of the Twelve-Membered Cyclodimer [Ph2BiN(SO2Me)2]2 and of the Ionic Complex [H(OAsPh3)2]⊕(MeSO2)2N⊖The novel bismuth(III or V) disulfonylamides Ph2BiN(SO2Me)2 (1), PhBi[N(SO2Me)2]2 (2), PhBi[N(SO2Me)2]Br (3), Bi[N(SO2Me)2]2Cl (4), Bi[N(SO2Me)2]Cl2 · 12-crown-4 (5) and Ph3Bi[N(SO2Me)2]Cl (6) were obtained by acidolysis of Ph3Bi with HN(SO2Me)2 (→ 1), by metathesis of AgN(SO2Me)2 with Ph2BiCl (→ 1) or PhBiBr2 (→ 2, 3), by condensation of BiCl3 with Me3SiN(SO2Me)2 (→ 4; in presence of 12-crown-4: → 5), or by oxidative addition of ClN(SO2Me)2 to Ph3Bi (→ 6). Independently of the molar ratio employed, triphenylarsane oxide and dimesylamine form the crystalline 2/1 complex [H(OAsPh3)2]⊕(MeSO2)2N⊖ (7). The crystal packing of 7 (monoclinic, space group C2/c) consists of discrete cations displaying crystallographic Ci symmetry and a strong O … H … O hydrogen bond (H atom located on a centre of symmetry, O … O′ 241.2 pm, As—O … O′ 120°, As—O 168.3 pm), and chiral anions with crystallographic C2 symmetry (N—S 157.3 pm, S—N—S 122,9°). In the solid state, the bismuth(III) compound 1 (triclinic, space group P1) is a cyclodimer with crystallographic Ci symmetry, in which two Ph2Bi⊕ cations are connected through two (α-O, ω-O)-donating dimesylamide ligands to form a roughly twelve-membered [BiOSNSO]2 ring (Bi—O 239.7 and 246.6, O—S 148.0 and 145.4, S—N 157.7 and 159.2 pm, Bi—O—S 126.6 and 127.5°). The bismuth atom adopts a pseudo-trigonal-bipyramidal geometry (O—Bi—O 165.4, C—Bi—C 93.0, O—Bi—C 83.8 to 86.5°). The essentially similar conformations of the discrete anion in 7 and of the bidentate bridging ligand in 1 are discussed in detail.
    Notes: Die neuartigen Bismut(III oder V)-disulfonylamide Ph2BiN(SO2Me)2 (1), PhBi[N(SO2Me)2]2 (2), PhBi[N(SO2Me)2]Br (3), Bi[N(SO2Me)2]2Cl (4), Bi[N(SO2Me)2]Cl2 · 12-Krone-4 (5) und Ph3Bi[N(SO2Me)2]Cl (6) entstanden durch Acidolyse von Ph3Bi mit HN(SO2Me)2 (→ 1), durch Metathese von AgN(SO2Me)2 mit Ph2BiCl (→ 1) oder mit PhBiBr2 (→ 2, 3), durch Kondensation von BiCl3 mit Me3SiN(SO2Me)2 (→ 4; in Gegenwart von 12-Krone-4: → 5) oder durch oxidative Addition von ClN(SO2Me)2 an Ph3Bi (→ 6). Triphenylarsanoxid bildet mit Dimesylamin, unabhängig vom benutzten Stoffmengenverhältnis, den kristallinen 2/1-Komplex [H(OAsPh3)2]⊕(MeSO2)2N⊖ (7). Die Kristallpackung von 7 (monoklin, Raumgruppe C2/c) besteht aus diskreten Kationen mit kristallographischer C--Symmetrie und einer starken O … H … O-Brücke (H-Atom auf einem Inversionszentrum lokalisiert, O … O′ 241,2 pm, As—O … O′ 120°, AS—O 168,3 pm) sowie chiralen Anionen mit kristallographischer C2-Symmetrie (N—S 157,3 pm, S—N—S 122,9°). Die Bismut(III)-Verbindung 1 (triklin, Raumgruppe P1) bildet im festen Zustand ein Cyclodimer mit kristallographischer Ci-Symmetrie, in welchem zwei Ph2Bi⊕-Kationen mit zwei (α-O, ω-O)-koordinierenden Dimesylamid-Liganden zu einem nur schwach gewellten zwölfgliedrigen [BiOSNSO]2-Ring verknüpft sind (Bi—O 239,7 und 246,6, O—S 148,0 und 145,4, S—N 157,7 und 159,2 pm, Bi—O—S 126,6 und 127,5°). Das Bismutatom ist ψ-trigonal-bipyramidal koordiniert (O—Bi—O 165,4, C—Bi—C 93,0, O—Bi—C im Bereich 83,8 bis 86,5°). Die sehr ähnlichen Konformationen des diskreten Anions in 7 und des zweizähnig-verbrückenden Liganden in 1 werden im einzelnen diskutiert.
