The triphenyltin(IV) complexes of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls (aryls = 4-CH3, 4-Br, 4-Cl, 4-OCH3) have been synthesized and characterized by 1H-, 13C-, 119Sn-NMR, ESI mass spectrometry, IR and 119mSn Mössbauer spectroscopic techniques in combination with elemental analysis. The crystal structures of a representative carboxylate ligand (aryl = 4-CH3) and three Sn complexes, viz., polymeric (Ph3Sn[O2CC6H4{NN(C6H3-4-OH(C(H)NC6H4X-4))}-o])n (X = Me (1) and Br (2)) and dimeric (Ph3Sn[O2CC6H4{NN(C6H3-4-OH(C(H)NC6H4X-4))}-o])2 (X = OMe (4)) complexes are reported. The coordination environment in each complex is trigonal bipyramidal trans-Ph3SnO2. A single zwitterionic carboxylate ligand bridges adjacent Sn atoms via the carboxylate and phenoxide O atoms.
The triphenyltin(IV) complexes of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls (aryls = 4-CH3 (1), 4-Br (2), 4-Cl (3) 4-OCH3 (4)) have been synthesized and characterized by 1H-, 13C-, 119Sn-NMR, ESI-mass spectrometry, IR and 119mSn Mössbauer spectroscopic techniques in combination with elemental analysis. X-ray crystallography reveals that complexes 1 and 2 adopt a polymeric form, while complex 4 is a cyclic dinuclear complex. The coordination environment in each complex is trigonal bipyramidal trans-Ph3SnO2. A single zwitterionic carboxylate ligand bridges adjacent Sn atoms via the carboxylate and phenoxide O atoms.Figure optionsDownload as PowerPoint slide
