【Abstract】 A mononuclear copper(Ⅱ) complexes, [(tacn)CuCl 2][(tacn)Cu(OH 2)Cl]ClO 4(tacn=1,4,7 triazacyclononane) has been synthesized and characterized by X ray single crystal analysis. Crystal data: orthorhombic, space group Pbca, a=1.31312(16)nm,b=1.8126(2)nm,c= 1.9288(2)nm, V=4.5907(9)nm 3,D x=1.763mg·m -3 ,z=8.The molecular structure of the complex shows that complex consists of two mononuclear copper unit and a ClO - 4 anion. In the molecule of complex two Cu(Ⅱ) ions are all five coordinate with distorted squarepyramid configuration. There are several hydrogen bonds in the crystal and the intermolecular H bonds interlink the molecules into a three dimensional network.更多还原
