Synthesis and Structure of(4-methylpyridine-N-oxide)oxo-(salicylaldehyde 4-phenylthiosemicarbazonato)vanadium(IV)

摘要

New title complex has been synthesized by the reaction of salicylaldehyde 4-phenylthiosemicarbazone with 4-methylp-yridine-N-oxide and[VO(acac)2].The tetragonal pyramidal coordination about vanadium atom is realized through O,N,S-donors of a doubly deprotonated thiosemicarbazonato ligand,oxygen atom from 4-methylpyridine-N-oxide molecule and in the apical position completed by an oxo group.The complex molecules are held together by hydrogen bonds and by pi-pi interactions between the aromatic rings of the ligand.The title complex has been characterized by chemical analysis,IR spectroscopy,TG and X-ray crystallography.
