Abstract: The reaction of CuCl2·2H2O with one equivalents of imidazole yields the coordination compound[Cu(im)6]Cl2·2H2O(1),[im=imidazole].Single-crystal X-ray analysis revealed that the complex 1 falls into monoclinic system,space group P21/n with a=0.8073(2)nm,b=1.3239(2)nm,c=1.50810(10)nm,β=97.940(10)°,R1=0.0434,wR2=0.1243.The equatorial ligands are involved into a complex hydrogen bond network that involves the chloride anions and uncoordinated water molecules.Thermal stability,IR spectrum and fluorescent property of the title compound are reported in the paper.
