Abstract

Based on an asymmetric 1,2,4‐benzenetricarboxylic acid (H3btc) and 2,2′‐bipyridine (bpy), a new CuII complex, Cu2(H2btc)4(bpy)2·8H2O (1), was synthesized and structurally characterized by single‐crystal X‐ray diffraction, hirshfeld surface (HS) analysis, IR spectroscopy, powder X‐ray analysis, thermal gravimetry analysis (TGA), magnetic susceptibility, EPR measurement, and UV/Vis spectrometry. Complex 1 shows a dinuclear copper structure. The CuII of each dinuclear moiety are in a slightly distorted square‐pyramidal environments. Magnetic susceptibility of 1 shows a ferromagnetic coupling between both metal atoms. The interaction of 1 with bovine serum albumin (BSA) is investigated using UV/Vis, fluorescence spectroscopic methods. The CuII complex shows strong binding propensity in albumin binding study.
