Abstract
The crystal structure of di-μ-chloro(dicyandiamide)cadmium(II) has been determined and refined by Fourier and least-squares methods toR = 0·037 using three-dimensional X-ray data collected at room-temperature on a single-crystal automated diffractometer. Crystal data are as follows:a = 10·796(7),b = 8·933(5),c = 6·847(3) Å,β = 99·9(1) °,Z = 4; space groupP21/n. The cadmium atom is surrounded by four chlorine (Cu-Cl = 2·572, 2·607, 2·630, 2·647 Å) and two nitrogen atoms (Cd-N (nitrilic) = 2·358 Å; Cd-N (guanidic) = 2·430 Å) so that the whole polyhedron appears as a slightly distorted octahedron. The chlorine atoms form bridges between adjacent metal atoms so that the coordination octahedra are linked in chains running along [001]. These chains are joined together by dicyandiamide bridges.
