oxodovanadium(V) complexes, [VO(L)(OEt)(MeOH)] (I) and [VO(L)(Bha)] · EtOH (II), where L is the anion of 2-chloro-N'-(3,5-dichloro-2-hydroxybenzylidene)benzohydrazide (H2L), Bha is the anion of 2-hydroxybenzohydroxamic acid (HBha), were prepared and characterized by IR, UV-Vis and single crystal X-ray determination (CIF files CCDC nos. 1840661 (I) and 1840662 (II)). Complex I crystallizes as the monoclinic space
spectroscopic and XRD data reveals that the ligand coordinates to palladium through ONO chelation and the geometry of the complexes is distorted square planar. The in vitro interaction of the synthesized compounds with calf-thymus DNA (CT-DNA) are analysed through different experiments which shows the intercalation mode of binding. Further, the interaction studies of the compounds with bovine serum
