Palladium(II) and platinum(II) complexes of deprotonated N,N′-bis(2-pyridinecarboxamide)-1,2-benzene: Synthesis, structural characterization and binding interactions with DNA and BSA

Structurally characterized two isomorphous tetracoordinated palladium(II) and platinum(II) complexes of deprotonated carboxamide (1a and 1b) have strong intercalative binding ability with CT-DNA through noncovalent bonding mode. The interactions of the complexes with bovine serum albumin (BSA) indicated the strong affinity of both of the complexes to BSA.
