Abstract Three cis ‐bis{5‐[( E )‐2‐(2‐carbomethoxyphenyl)‐1‐diazenyl]quinolinolato}‐diorganotin(IV), R 2 Sn(L) 2 , complexes [ R = Me ( 1 ), Ph ( 2 ) and Bz ( 3 )] were synthesized and characterizedby 1 H‐, 13 C‐, 119 Sn‐ NMR, IR, and 119 Sn Mössbauer spectroscopic techniques in combination with elemental analysis. The structure of diphenyltin(IV) complex Ph 2 Sn(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.
