摘要
A series of tributyltin(IV) complexes of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(aryl)-1-diazenyl]phenyl}methylidene)amino]benzoates have been investigated by 1H, 13C, 119Sn NMR, IR and 119Sn Mössbauer spectroscopic techniques in combination with elemental analyses. Single crystal X-ray crystallography of Bu3Sn[O2CC6H4{N=C(H)C6H3-2-OH(N=NC6H4CH3-4)}-p] reveals a distorted tetrahedral structure which is further supported by 119Sn Mössbauer data. Toxicity studies of the tributyltin(IV) complexes along with their ligands 4-[((E)-1-{2-hydroxy-5-[(E)-2-(aryl)-1-diazenyl]phenyl}methylidene)amino]benzoic acids on the second larval instar of the Anopheles stephensi mosquito larvae are also reported.
