Synthesis and Crystal Structure of a Cu(HTren)Cl2ClO4·H2O Complex (Tren = Tris(2-aminoethyl)amine)

摘要

The title complex [Cu(HTren)Cl2]ClO4·H2O (Tren = tris(2-aminoethyl)amine) was crystal (CuC6H21Cl3N4O5) is of triclinic, space group P-1, with a = 8.2689(2), b = 8.4503(3), c=11.6801(4)(A), a = 96.9350(10), β= 108.2440(10), γ = 90.7550(10)°, V= 768.32(4)(A)3, Z= 2, Mr=399.16, Dc= 1.725 g/cm3,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.
