Abstract: A new complex, [Cu2(μ 2-Cl)2(IP)2Cl2] · 4H2O (IP = imidazo[4,5-f]1,10-phenathroline), was synthesised and characterised by elemental analysis, thermal analysis, IR spectra, and X-ray crystallography. The results showed that the complex crystallises in the monoclinic space group P1; a = 7.880 (2) Å, b = 9.227(2) Å, c = 10.694(2) Å; α = 97.788(4)°, β = 100.637(4)°, γ = 95.841(3)°; V = 750.7(3) Å3, and Z = 1. The complex is further stabilised by H-bonds and a π-π stacking interaction between the pyridine and benzene rings of two neighbouring molecules with the centroid.centroid distance of 3.498(3) Å, leading to a 3D supramolecular architecture. Thermal decomposition procedure of the complex explored by TG-DTG has three stages, and the final product is Cu in residual rate of 16.18 % (calculated to be 16.26 %).

Keywords: imidazo[4,5-f]1,10-phenathroline – copper(II) complex – crystal structure – thermal analysis
