    Description / Table of Contents: Polysulfonyl Amines. LVII. Two Silver(I) Di(organosulfonyl)-amides with Silver-η2-Aryl or Silver-Silver Interactions: Crystal Structures of Silver Di(benzenesulfonyl)amide-Water (1/0.5) and of Anhydrous Silver Di(4-toluenesulfonyl)-amideCrystals of [(PhSO2)2NAg(μ-H2O)AgN(SO2Ph)2]n (5) and [(4-Me—C6H4SO2)2NAgAgN(SO2C6H4-4-Me)2]n (6) were obtained from aqueous solutions. The crystallographic data are for 5 (at -95°C): monoclinic, space group C2/c, a = 2 743.8(5), b = 600.49(12), c = 1 664.5(3) pm, β = 101.143(15)°, V = 2.6908 nm3, Z = 8, Dx = 2.040 Mg m-3; for 6 (at -130°C): monoclinic, space group P21/n, a = 1 099.8(5), b = 563.7(3), c = 2 487.7(13) pm, β = 99.68(4)°, V = 1.5203 nm3, Z = 4, Dx = 1.888 Mg m-3. In both crystals, the silver atom has a fivefold coordination. The structure of 5 displays [(RSO2)2N—Ag(μ-H2O)Ag′—N(SO2R)2] units with Ag—N 226.9 pm, Ag—O 236.7 pm and Ag—O—Ag′ 95.3°; the water oxygen lies on a crystallographic twofold axis. These units are extended to two fused six-membered rings by intramolecular dative bonds (S)O → Ag′ and S(O)′ → Ag (249.3 pm). One phenyl group from each (PhSO2)2N moiety is η2-coordinated with its p-C and one m-C atom to a silver atom of a neighbouring bicyclic unit related by a glide plane to form infinite parallel strands (p-C—Ag 252.2, m-C—Ag 263.9 pm). The strands are interconnected into parallel layers through hydrogen bonds between H2O and sulfonyl oxygens [O … O(S) 276.1 pm]. These layers consist of a hydrophilic inner region containing metal ions, N(SO2)2 fragments and water molecules, and hydrophobic surfaces formed by phenyl groups. The structure of 6 features centrosymmetric [(RSO2)2N—Ag—Ag′—N(SO2R)2] units with two intramolecular dative bonds (S)O → Ag′ and (S)O′ → Ag (Ag—Ag′ 295.4, Ag—N 226.0, Ag—O 229.4 pm). These bi-pentacyclic units are associated by translation parallel to y into infinite strands by two dative (S)O → Ag bonds per silver atom (Ag—O 243.2 and 253.3 pm).
    Notes: Kristalle von [(PhSO2)2NAg(μ-H2O)AgN(SO2Ph)2]n (5) und [(4-Me—C6H4SO2)2NAgAgN(SO2C6H4-4-Me)2]n (6) wurden aus Wasser erhalten. Die kristallographischen Daten sind für 5 (bei -95°C): monoklin, Raumgruppe C2/c, a = 2 743,8(5), b = 600,49(12), c = 1 664,5(3) pm, β = 101,143(15)°, V = 2,6908 nm3, Z = 8, Dx = 2,040 Mg m-3; für 6 (bei -130°C): monoklin, Raumgruppe P21/n, a = 1 099,8(5), b = 563,7(3), c = 2 487,7(13) pm, β = 99,68(4)°, V = 1,5203 nm3, Z = 4, Dx = 1,888 Mg m-3. Das Silberatom ist in beiden Verbindungen pentakoordiniert. Die Struktur von 5 enthält Einheiten des Typs [(RSO2)2N—Ag(μ-H2O)Ag′—N(SO2R)2] mit Ag—N 226,9 pm, Ag—O 236,7 pm und Ag—O—Ag′ 95,3°; das Wasser-O-Atom liegt auf einer kristallographischen zweizähligen Achse. Durch intramolekulare dative Bindungen (S)O → Ag′ und S(O)′ → Ag (249,3 pm) entstehen zwei kondensierte Sechsringe. Ein Phenylring aus jeder (PhSO2)2N-Gruppe geht mit dem p-C- und einem m-C-Atom eine η2-Wechselwirkung mit einem Ag-Atom eines benachbarten Bicyclus ein (p-C—Ag 252,2, m-C—Ag 263,9 pm). Auf diese Weise bilden sich unendliche parallele Stränge, in welchen die obigen Repetiereinheiten über eine Gleitspiegelebene miteinander in Beziehung stehen. Die Stränge sind durch Wasserstoffbrücken zwischen H2O und Sulfonyl-O-Atomen [O … O(S) 276,1 pm] zu parallelen Schichten verknüpft. Diese besitzen einen hydrophilen inneren Bereich aus Metallkationen, N(SO2)2-Fragmenten und Wassermolekülen und hydrophobe, von Phenylgruppen gebildete Oberflächen. Die Struktur von 6 enthält zentrosymmetrische [(RSO2)2N—Ag—Ag′—N(SO2R)2]-Einheiten mit zwei intramolekularen dativen Bindungen (S)O → Ag′ und (S)O′ → Ag (Ag—Ag 295,4, Ag—N 226,0, Ag—O 229,4 pm). Diese bipentacyclischen Einheiten sind über zwei dative (S)O → Ag-Bindungen pro Silberatom (Ag—O 243,2 und 253,3 pm) zu unendlichen Strängen parallel zur y-Achse assoziiert. Innerhalb des Stranges stehen sie durch Translation miteinander in Beziehung.

    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.
