It crystallizes in the monoclinic system, space group C2/c with lattice parameters a=1.49071(4)nm, b=1.38594(4)nm, c=0.70292(1)nm, β =108.509(1)° and Z=4; The Cu? ion is chelated by a phen ligand and two aqua ligands in cis arrangement and assumes a C2 symmetric square planar geometry with the CuN2O2 core. Eight Cu(phen)(H2O)2· ClO4 molecules are interconnected by strong hydrogen bonds between coordinated water molecules and uncoordinated perchlorate anions to form a molecular scale cavities along c axis. The bond distances of Cu N and Cu O are 0.2003(4)nm and 0.1973(3)nm, respectively. CCDC: 197600.展开更多
