Synthesis, Characterisation and Thermal Properties of Sn(II) Pyrrolide Complexes

Abstract

SnO is a rare example of a stable p-type semiconductor material. Here, we describe the synthesis and characterisation of a family of Sn(ii) pyrrolide complexes for future application in the MOCVD and ALD of tin containing thin films. Reaction of the Sn(ii) amide complex, [{(Me 3Si) 2N} 2Sn], with the N,N-bidentate pyrrole pro-ligand, L 1H, forms the hetero- and homoleptic complexes [{L 1}Sn{N(SiMe 3) 2}] (1) and [{L 1}2Sn] (2), respectively, bearing the 2-dimethylaminomethyl-pyrrolide ligand (L 1). Reaction of [{(Me 3Si) 2N)} 2Sn] with the pyrrole-aldimine pro-ligands, L 2H-L 7H, results in the exclusive formation of the homoleptic bis-pyrrolide complexes [{L 2-7} 2Sn] (3-8). All complexes have been characterised by elemental analysis and NMR spectroscopy, and the molecular structures of complexes 1-5 and 8 are determined by single crystal X-ray diffraction. TG analysis and isothermal TG analysis have been used to evaluate the potential utility of these systems as MOCVD and ALD precursors.
