Rezumat

Three mononuclear dioxovanadium(V) complexes, [VO 2 (HL 1 )] 1 ), [VO 2 (HL 2 )]∙1.2H 2 O 2 ) and [VO 2 (HL 3 )]∙DMF∙H 2 O ( 3 ) with tridentate ONO ligands derived from isonicotinoylhydrazide and salicylaldehyde (H 2 L 1 ), o vanillin (H 2 L 2 ) and 3 carboxy salicylaldehyde (H 2 L 3 ), respectively, have been synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X Ray diffraction studies. The V(V) in all complexes has a distorted square pyramidal geometry with ONOO2 donor atoms set.
