    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.

Synthesis and Crystal Structure of [(Ph3PAu)5Mo(CO)4]PF6 · CH2Cl2 and (Ph3PAu)3Co(CO)3Photolysis of a mixture of Ph2PAuN3 and Mo(CO)6 in THF yields [(Ph3PAu)5Mo(CO)4]+ (1), which can be crystallized from CH2Cl2/diisopropylether as orange 1 · PF6 · CH2Cl2 with the space group P21/c and a = 1681.4(5), b = 2215.6(12), c = 2761.5(9) pm, β = 91.54(3)°, Z = 4. The Au5Mo center of cluster 1 forms a capped trigonal bipyramid with the Mo atom in equatorial position and almost equal Mo—Au distances between 279.9(5) and 284.6(7) pm to all five Au atoms. The Au—Au distances range from 272.2(4) to 301.3(4) pm. The Mo(CO)4 group causes three v(C0) at 1975, 1915 and 1890cm-1. Reaction of Ph3PAuCo(CO)4 with Ph3PAuPF6 affords the known cluster cation [(Ph3PAu)4Co(CO)3]+ in high yield. It can be degraded with C1- to the neutral cluster (Ph3PAu)3Co(CO)3 (2). 2 forms air stable, yellow crystals with the space group P21/n and a = 1359.4(4), b = 2041.0(5), c = 1853.2(6)pm, β = 91.47(1)°, Z = 4.

Die Au—Au-Abstände liegen zwischen 272,2(4) und 301,3(4) pm. Die Valenzschwingungen v(Co) der Mo(CO)4-Gruppe werden bei 1975, 1915 und 1890cm-1 beobachtet. Reaktion von Ph3PAuCo(CO)4 mit Ph3PAuPF6 liefert das bereits bekannte Clusterkation [(Ph3PAu)4C(CO)3]+ in hoher Ausbeute.

The crystal structure was determined from single crystal four-circle diffractometer data (R3, Z = 6, a = 1175.5(1), c = 1117.7(2) pm, Vm = 134.25 cm3/mol, R = 3.0%, Rw = 2.9%). The structure may be viewed at as a heavily compressed packing of [Yb(H2O)3(NO3)3] molecules. Yb3+ is coordinated by three bidentate nitrate ligands and three water molecules so that a tricapped trigonal prism (C.N. 9) of oxygen atoms results as the coordination polyhedron.

Sie kann als stark gestauchte Kugelpackung von [Yb(H2O)3(NO3)3]- Molekülen aufgefaßt werden.
