摘 要: | 1INTRODUCTION Investigation of the coordination chemistry of copper(II)continues to be stimulated by interest in developing modes for copper proteins and in under-standing the factors which give rise to the seemingly infinite variety of distortions from regular stereo-chemistry observed in Cu(II)complexes[1,2].For more than decades,due to the unique coordination polyhedra and their easy preparation,tripodal copper complexes have attracted much attention in addition to their special chemi…

Abstract: | 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, a = 96.9350(10), β = 108.2440(10), γ = 90.7550(10)°, V = 768.32(4) ·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) ·, respectively. The whole crystal presents a three-dimensional network structure by hydrogen bonds. |
