catena-Poly[[tri-methyl-tin(IV)]-μ-3,4-di-fluoro-benzene-seleninato-κ2O:O′]

摘要

The title compound, [Sn(CH3)3(C6H3F2O2Se)]n, was prepared by treatment of 3,4-difluorobenzeneseleninic acid and trimethyltin chloride with sodium ethoxide in methanol. In the polymeric crystal structure, infinite chains, with the SnIV atom in a trigonal–bipyramidal C3O2 coordination environment involving methyl ligands and the bridging 3,4-difluorobenzeneseleninate anion, are present. The chains extend parallel to [010] and are linked through slipped – interactions and weak C—HO hydrogen bonds into a three-dimensional network.
