Abstract
Compositions and structures of two mixed complexes of chromium and zin c chlorides with carbamide-[Cr(CON2H4)(6)](3+)[ZnCl4]Cl-2-(-). 2H(2)O (I) and [Cr(CON2H4)(6)](3+)[ZnCl4](2-)[ZnCl3(CON2H4)](-) (II)-were det ermined by single-crystal X-ray diffraction analysis (sp. gr. P (1) ov er bar for I and II; Z= 2 and 1; R = 0.032 and 0.054 for 3498 and 3826 reflections, respectively). In structure II, one of the Cl atoms and the carbamide molecule bound to the Zn atom are statistically disorder ed. The symmetry of the [Cr(CON2H4)(6)](3+) cation approximates 32 in structure I and (3) over bar in structure II.
