“…A central question in the structural chemistry of triorganotin(IV) carboxylates is whether carboxylate groups will chelate to form monomers with four-coordinate tin or give five-coordinate polymers as a result of carboxylate bridging (Amini, Ng, Fidelis, Heeg, Muchmore, van der Helm & Zuckerman, 1989). Triphenyltin(IV) arylcarboxylates are generally monomeric molecules with tetrahedral tin (Ng, Kumar Das, van Meurs, Schagen & Strayer, 1989); the aryl group prefers to be conjugated to the carboxylate group and to be coplanar with it.…”
