Synthesis, spectroscopic characterization of tribenzyltin(IV) complexes of polyaromatic carboxylic acid ligands: Crystal and molecular structures of Bz3Sn[O2CC6H4{NN(C6H3-4-OH(C(H)NC6H4X-4))}-o](OH2) (X = –Cl, –OCH3)

The tribenzyltin(IV) complexes of 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid and 2-{(E)-4-hydroxy-3-[(E)-4-(aryl)iminomethyl]phenyldiazenyl}benzoic acids (aryls = 4-CH3, 4-Br, 4-Cl, 4-OCH3) have been synthesized and characterized by 1H, 13C, 119Sn NMR, IR and 119mSn Mössbauer spectroscopic techniques in combination with elemental analysis. The crystal structures of two monomeric tribenzyltin(IV) complexes, Bz3Sn[O2CC6H4{NN(C6H3-4-OH(C(H)NC6H4X-4))}-o](OH2) (X = –Cl and –OCH3) are reported. The coordination environment in each complex is trigonal bipyramidal trans-Bz3SnO2.
