formed deep red-colored block crystals through the slow evaporation of the solvent at room temperature. The single-crystal X-ray diffraction (SCXRD) revealed Cu58-I NC crystallizes in a trigonal crystal system with a P-3 (No. 147) space group (Table ). While Cu58-II NC crystallizes in a triclinic crystal system with a P-1 (No. 2) space group (Table ).
