O,N-Chelated germanium, tin and lead compounds containing 2-[N,N-(dimethylamino)methyl]phenolate as ligand

Thirteen organotin(IV) and low valent complexes of group 14 (Ge, Sn, Pb) containing LNO ligand(s) (where LNO is 2-(N,N-dimethylaminomethyl)phenolate) were synthesized and its structure described by NMR techniques in solution and X-ray techniques in the solid state (for L2NOSnPh2, L2NOSnCl2, L2NOGe and LNOSnCl which forms a dimer). Structures and properties of prepared species have been compared with previously published germanium and tin compounds containing –OCH2CH2NMe2 as O,N- or LCN (where LCN is 2-(N,N-dimethylaminomethyl)phenyl) as C,N-chelating ligands. The solid state structures containing LNO ligand(s) reveal much stronger intramolecular N → Sn coordination than complexes containing latter two ligands.
