摘要：
The crystallographic structure of [C4H6N3O]2[CuCl4] is as follows: triclinic, P.hivin.1, a = 13.689, b = 9.537, c = 6.936 .ANG., .alpha. = 102.93, .beta. = 105.59, .gamma. = 112.24, Z = 2, Dm = 1.875 Mg m-3. The final R value is 0.082 for 2711 non-zero reflections observed on a diffractometer. There is no direct coordination between the metal atoms and cytosinium cations. The base pairing related by a center of symmetry is formed by 2 N.sbd.H.cntdot..cntdot..cntdot.O hydrogen bonds (2.85 .ANG.). The main intermolecular interactions consist of 5 kinds of N.sbd.H.cntdot..cntdot..cntdot.Cl hydrogen bonds.
