摘要:
The tri-n-butyltin(IV) complexes of 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid and 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 H-1, C-13, Sn-119 NMR, IR and Sn-119m Mossbauer spectroscopic techniques in combination with elemental analysis. The crystal structures of two compounds, (Bu3Sn[O2CC6H4{N=N(C6H3-4-OH-5-CHO)}-o])(n) and (Bu3Sn[O2CC6H4{N=N(C6H3-4-OH(C(H)=NC6H4Cl-4))}-o])(n), are reported. The crystallographic and Sn-119 Mossbauer data both indicate that the tributyltin complexes form single-stranded polymeric structures in which the carboxylate O atoms of each aryl ligand bridge two Sn atoms. The Sn atoms have a slighly distorted trigonal bipyramidal coordination geometry with equatorial butyl groups and carboxylate O atoms occupying axial positions. The Sn-119 NMR spectroscopic data and the (1)J(C-13-Sn-119/117) coupling constant indicate a tetrahedral coordination geometry in non-coordinating solvents. The results of a toxicity study of a tributyltin compound on the second larval instar of Aedes aegypti mosquito larvae are reported. (C) 2004 Elsevier B.V. All rights reserved.

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 H-1-, C-13-, Sn-119-NMR, ESI mass spectrometry, IR and Sn-119m Mossbauer 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[O2CC6H4N=N(C6H3-4-OH(C(H)= NC6H4X-4))}-o])(n) (X = Me (1) and Br (2)) and dimeric (Ph3Sn[O2CC6H4N=N(C(6)H(3)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 Sit atoms via the carboxylate and phenoxide O atoms.
