  二聚二有机锡 (IV) 氢氧化物 [Me2Sn(A)(μ-OH)]2 (HA = 苯-1,2-二磺酸酰亚胺) 的破坏性络合：单核络合物 [Me2Sn(A)2( OPPh3)2] 和 [Me2Sn(phen)2]2⊕ 2 A⊖ MeCN

  摘要：

  Destructive complexation of the dimeric hydroxide [Me2Sn(A)(mu-OH)](2), where A(-) is deprotonated benzene-1,2-disulfonimide, with two equivalents of triphenylphosphine oxide or 1,10-phenanthroline in hot MeCN produced, along with Me2SnO and water, the novel coordination compounds [Me2Sn(A)(2)(OPPh3)(2)] (3, triclinic, space group P (1) over bar) and [Me2Sn(phen)(2)](2+) . 2A(-) . MeCN (4, monoclinic, P2(1)/c). In the uncharged all-trans octahedral complex 3, the heteroligands are unidentally O-bonded to the tin atom, which resides on a crystallographic centre of inversion [Sn-O(S) 227.4(2), Sn-O(P) 219.6(2) pm, cis-angles in the range 87-93 degrees, anionic ligand partially disordered over two equally populated sites for N, two S and non-coordinating O atoms]. The cation occurring in the crystal of 4 has a severely distorted cis-octahedral C2N4 coordination geometry around tin and represents the first authenticated example of a dicationic tin(IV) dichelate [R2Sn(L-L')(2)](2+) to adopt a cis-structure [C-Sn-C 108.44(11)degrees]. The five-membered chelate rings are nearly planar, with similar bite angles of the bidentate ligands, but unsymmetric Sn-N bond lengths, each of the longer bonds being trans to a methyl group [ring 1: N-Sn-N 71.24(7)degrees, Sn-N 226.81(19) and 237.5(2)pm; ring 2: 71.63(7)degrees, 228.0(2) and 232.20(19)pm]. In both structures, the bicyclic and effectively Cs symmetric A(-) ions have their five-membered rings distorted into an envelope conformation, with N atoms displaced by 28-43 pm from the corresponding C6S2 mean plane.
