Synthesis, Crystallography, and Antibacterial Activity of a New Cocrystal Copper-Cerium Based on 1,10-Phenanthroline

The cocrystal Copper-Cerium based on 1, 10-phenanthroline, [Cu(Phen)3][Ce(Phen)(NO3)5] (C), was synthesized by condensation of Ce(NO3)3.6H2O, Cu(ClO4)2, and 1, 10- phenanthroline in ethanol solution. Newly synthesized cocrystal was characterized by FT-IR, UV-Vis, and elemental analysis. The crystal structure of C was determined by X-ray crystallography. Antibacterial activity of compounds was evaluated against two gram-positive S. aureus, S. saprophyticus and one gram-negative P. aeruginosa bacteria, by the disk-diffusion method. The antibacterial efficacy of the compounds in the concentration range of 10–40 μg/D is demonstrated by determining the inhibition zone.
