Abstract
The crystal structures of the title compounds, (C2N3H8)(2)-[CuCl4], (I), an d (C8H14N4)[CuCl4],(II), have been studied by X-ray diffraction. The struct ures consist of discrete [CuCl4](2-) anions with two monoprotonated (C2N3H8 )(+) cations for (I) and a diprotonated (C8N4H14)(2+) cation for (II). The [CuCl4](2-) anions of both compounds have flattened tetrahedral geometries. There are several N-H ... Cl weak bonds that join the [CuCl4](2-) anions a nd the organic cations helping retain the pseudo-tetrahedral geometries of the anions.
