1:1 Adducts of dimethyltin (IV) dichloride forming six-co-ordinated solids

Abstract

The crystal structures of the 1:1 adducts of dimethyltin (IV) dichloride with diphenylcyclopropenone and with 2, 6-dimethylpyridine (2,6-lutidine)N-oxide reveal dimer formation through bridging chlorine atoms to create six-co-ordination at tin, and the structure of the 1:1 salicylaldehyde adduct is reinterpreted in similar terms as an associated solid with bridging phenolic oxygen atoms; Mössbauer quadrupole splitting data, where available, corroborate the suggestion of six-co-ordination for the known 1:1 complexes.
