摘要
Two complexes, [Et4N](2)[Sn(dmit)(3)], 1, and [Pb(dmit)(DMF)](n), 2, have been obtained and their structures crystallographically determined. In complex 1, the Sn atom is six-coordinated to six sulfur atoms from three dmit ligands; the anions form a one-dimensional network through S ... S contacts shorter than 3.7 Angstrom. Complex 2 forms a two-dimensional polymer, achieved through Pb atom coordinating not only to the chelating sulfur atoms of the dithiolate fragment of dmit, but also to the sulfur atom of the thiocarbonyl group of a dmit ligand. In complex 2, the central Pb atom is six-coordinated by four sulfur atoms from dmit ligands and two oxygen atoms of N,N-dimethylformamide ligands, exhibiting a distorted octahedral structure.
