  Synthesis and crystal structures of diorganotin dicyanoethylene-1,2-dithiolate compounds and their derivatives with 4,4′-Bipy or Phen

  摘要：

  Six diorganotin(IV) compounds with dicyanoethylene-1,2-dithiolate (mnt) of the type [R2Sn(mnt)ClnL] . Y (when n = 0, L = 0: R = CH3, y = 0, 1; R = n-Bu, Y = 0, 2; R = C6H6, Y = 0.5C(6)H(6), 3; R = CH3, Y = 1,5(4,4'-Bipy), 4; when n = 1, L = 0, R = CH3, Y = 4,4'-Bipy 5; when n = 0, L = Phen, R = CH3, Y = 0, 6; 4,4-Bipy = 4,4'-bipyridyl; Phen = 1,10-phenanthroline) are synthesized by the reaction of diorganotin dichloride and disodium maleonitriledithiolate (Na(2)mnt) in the presence of 4,4'-Bipy or Phen. All the compounds 1-6 are characterized by elemental, IR, H-1 NMR spectroscopy and X-ray crystallography analyses. The X-ray data showed the geometries of all the tin atoms in compounds 1-4 are tetrahedral, and those in 5 and 6 are trigonal bipyramidal and distorted octahedral, respectively. Co-crystallization is found in crystals of compounds 3 and 4. The co-crystallized solvents are benzene and 4,4'-Bipy, respectively. Compound 5 is a stannate with a five-coordinated tin(IV) atom. Compound 6 is a six-coordinated dimethyltin(IV) derivative from mixed ligands of mnt and Phen. (C) 2004 Elsevier Ltd. All rights reserved.

The formation of dimetallic [(R2C2S2)M(tpbz)M(S2C2R2)] attends these syntheses in modest amounts, but the open-ended compounds are readily separated by silica chromatography. As affirmed by X-ray
