摘要
The reactivity of the polydentate ligands bis(2-acetylpyridine) carbonohydrazone (H(2)apc) and 2-acetylpyridine semicarbazone (Haps) as well as of their sulphur containing analogous bis(2-acetylpyridine) thiocarbonohydrazone (H(2)apt) and 2-acetylpyridine thiosemicarbazone (Hapts) was investigated towards organotin compounds. An X-ray crystal structure determination carried out on Ph2Sn(Hapt)Cl . H2O (1) and (n-Bu)(2)Sn(apts)(OAc) (5) revealed that in both compounds the hydrazonic ligand is terdentate via a sulphur atom and two nitrogen atoms. The tin atom is six-coordinated in 1 and seven-coordinated in 5. The similarities observed in the IR and H-1 NMR spectra are indicative of a similar behaviour of the ligand in all the complexes, thus suggesting a six-coordinated tin in the chloro derivatives and a seven-coordinated tin in the acetato ones.
