摘　　要：The title complex [Cu（HTren）Cl2]ClO4·H2O （Tren = tris（2-aminoethyl）amine） was synthesized by the reaction of Cu（ClO4）2·6H2O with Tren.3HCl in water and methyl alcohol. The crystal （CuC6H21Cl3N4O5） is of triclinic, space group P1, with a = 8.2689（2）, b = 8.4503（3）, c = 11.6801（4） A, α= 96.9350（10）, β= 108.2440（10）, y = 90.7550（10）°, V= 768.32（4）A^3, Z = 2, Mr= 399.16, D,.= 1.725 g/cm^3,μ= 1.962 mm^-1, F（000） = 410, T= 293（2） K, the final R = 0.0479 and wR = 0.1339 for 2659 observed reflections with I 〉 2σ（I）. X-ray single-crystal structure analysis reveals that the copper（Ⅱ） atom adopts a slightly distorted square-pyramidal geometry. The distances between Cu and N atoms （N（1）, N（2）, N（3）） range from 1.975（4） to 2.116（3）A,. The bond lengths of Cu-Cl（1） and Cu-Cl（2） are 2.309（10） and 2.591（10） A, respectively. The whole crystal presents a three-dimensional network structure by hydrogen bonds.The title complex [Cu（HTren）Cl2]ClO4·H2O （Tren = tris（2-aminoethyl）amine） was synthesized by the reaction of Cu（ClO4）2·6H2O with Tren.3HCl in water and methyl alcohol.
