摘要

Three cis-bis{5-[(E)-2-(2-carbomethoxyphenyl)-1-diazenyl]quinolinolato}- diorganotin(IV), R _2Sn(L) _2, complexes [R = Me (1), Ph (2) and Bz (3)] were synthesized and characterizedby ~1H-, ~(13)C-, ~(119)Sn- NMR, IR, and ~(119)Sn M?ssbauer spectroscopic techniques in combination with elemental analysis. The structure of diphenyltin(IV) complex Ph _2Sn(L) _2 (2) was determined by single-crystal X-ray crystallography as its tri-benzene solvate. Each complex was found to adopt a distorted cis-R _2 octahedral arrangement around the tin atom with the quinolinolato ligands being N,O-chelating; the oxygen atoms are trans to each other. The complexes retain their solid-state structure in non-coordinating solvents as evidenced by ~(119)Sn-NMR spectroscopy.
