Abstract
Two water-soluble dicationic complexes, [Cu(bipy)(dipn)](BF4)(2) (1) and [Cu(bipy)(dipn)](NO3)(2) (2) (bipy = 2.2-bipyridine and dipn = dipropylenetriamine), were synthesized in high yields. The desired complexes were characterized by CHN-EA, UV-Vis, SEM, EDS, FT-IR, TGA, and XRD. The single-crystal XRD of [Cu(bipy)(dipn)](BF4)(2) reflected that Cu(II) complex is formed in a distorted square pyramid configuration. The Hirshfeld surface analysis (HSA) confirmed more powerful atom-atom interaction, the hydrogen bonding in H horizontal ellipsis F, supporting the outcome of XRD. The influences of the CT-DNA/complexes were gathered by viscosity, CV, and electronic absorption measurements. The estimated binding constants (K-b) for 1 and 2 were 4.5 x 10(4) and 3.4 x 10(4) M-1, respectively. Complex 2 revealed slightly poorer DNA binding capability than 1. Eventually, the molecular docking of [Cu(bipy)(dipn)](+2) species was evaluated and demonstrated employing 1BNA-DNA segment.
