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

New title complex has been synthesized by the reaction of salicylaldehyde 4-phenylthiosemicarbazone with 4-methylpyridine- 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 p–p interactions between the aromatic rings of the ligand. The title complex has been characterized by chemical analysis, IR spectroscopy, TG and X-ray crystallography.
