Abstract
The current research work shows a novel oxovanadium (IV) complex (VC12O6H20N4) by the reaction of VO(acac)2 and DCDA (where acac = acetylacetonate and DCDA = dicyandiamide) as ligand. The synthesized oxovanadium (IV) complex was characterized by different techniques used for elemental analysis, IR, ESR,TG-DTA, XRD, and biological studies. The IR spectra show that the bands associated with [V=O], [V-O], and [V-N] might be assigned to 948 cm-1, 462 cm-1, and 527 cm-1, respectively. The analysis of ESR spectral studies indicates that the eight-line pattern denotes the presence of a single vanadium atom and the monomeric structure of the complex. According to TG curve reveals that the first and second weight loss of the synthesized complex is found at 5.23% and 69.45% due to lattice water molecules and the release of two acetylacetonate molecules and one dicyandiamide molecule. The oxo-vanadium complex's average crystallite size is 76 nm by using Debye Scherer's formula. In biological studies, the complex can interact with CT-DNA through electrostatic binding, causing a small increase in Tm by thermal denaturation. The cyclic voltammetry indicates that the EPA values are shifted to a more negative potential with increasing concentrations of CT-DNA also through electrostatic binding.
