| 摘 要： | <正> CuC6H21N5O8Cl2, Mr = 425. 5, monoclinic, P21/n, a = 8. 418 (2), b = 14.450(4), c= 12. 940(3)A, β=98. 13(2)% V = 1572. 9A3,Z = 4, Dx= 1. 797g. cm-3,μ(MoKa) = 18. 3cm-1. The crystal structure consists of discrete complex cations and perchlorate anions. The coordination geometry around Cu(Ⅱ) atom is a distorted square pyramid. The complex cations are disordered in the crystal,the ethylenediamine ligand chelates to the Cu(Ⅱ ) atom in δ arid λ conformation in different cells. The average Cu-N distance is 2. 03 A in the equatorial plane while the Cu -N distance is 2. 25 A in the axial direction.
