| Abstract: | ABSTRACT A new oxovanadium (IV) complex VO(acac)2DCDA]H2O (where acac = acetylacetonate; DCDA = dicyandiamide) was synthesized and characterized by elemental analysis, IR, UV, ESR, TG-DTA analysis and powdered XRD. The electronic and ESR spectral studies indicate the monomeric nature of the complex having distorted octahedral structure. The complex shows prominent emission peak at 485 nm and excitation peak at 355 nm. The cyclic voltammetry study shows irreversible process. DNA binding study of the complex with CT-DNA indicates nonintercalative mode with binding constant 2.063 × 102 M?1. |
