Notes:
The crystal structure of anhydrous chromium dichloride (CrCl2) has been determined by the X-ray powder method. CrCl2 has an orthorhombic elementary cell with a = 6,624 ± O.006 Å b = 5,974 ± 0,006 Å, c = 3,488 ± 0,004 Å, space group D2h12-Pnnm. The values for the only free parameters xcl and ycl have been refined by a least squares treatment. The structure of CrCl2 is related to the PdCl2 structure and, as expected from the crystal field theory, to the structure of CuCl2. Each Cr atom is surrounded nearly quadratically by four Cl atoms at a distance of 2,375 Å and two Cl atoms at 2,91 Å, completing a deformed octahedron.
