A series of tin (II) amido complexes possessing m-terphenyl carboxylate ligands have been prepared. These complexes, namely [(Me3Si) 2NSn (µ-O2CC6H2Ph3)] 2,[(Me3Si) 2NSn (µ- O2CC6H3Mes2)] 2, and [(Me3Si) 2NSn (µ-O2CC6H2Mes2Me)] 2 [Mes= 2, 4, 6- trimethylphenyl], are the first structurally characterized examples of tin (II) carboxylate complexes exhibiting discrete Sn2O4C2 heterocyclic cores. Initial reactivity studies led to ...
