Synthesis, characterisation and reaction chemistry of organotin-substituted bis(thiotetrazoles): supramolecular metallotetrazole structures containing hard and soft donors

Abstract

Four new organotin thiotetrazoles 1,4-(R₃SnSCN₄)₂C₆H₄ (R = Me, Et, Bu or Ph), along with their triphenyllead, diphenylthallium and phenylmercury analogues, have been synthesized. The supramolecular structure of 1,4-(Bu₃SnSCN₄)₂C₆H₄ has been found to consist of a 2-D sheet arrangement containing 32-membered (C₄NCSSnN₂CSSnN₃)₂ rings. In contrast, 1,4-(Me₃SnSCN₄)₂C₆H₄ crystallises as a bis(methanol) solvate in which 14-membered (SnSCN₂HO)₂ rings are linked through hydrogen bonds into a 1-D polymer.
