Tetramethylammonium tetraaquadichlorochromium(III) trichloride dihydrate

A. K. Eriksson, B. M. Casari and V. Langer

Abstract: The title metal-organic octahedral chromium compound, (C₄H₁₂N)₂[CrCl₂(H₂O)₄]Cl₃·2H₂O, was synthesized according to the Palmer method. The chromium complex ion possesses mirror symmetry and has two axial Cl^- ions and four equatorial water molecules. The octahedral complex cation and tetramethyl ammonium tetrahedra pack in a `parquet'-style pattern, with Cl<sup>-</sup> ions and water molecules in between the `bricks'. The structure is compared with aquapentachlorochromate(III) complexes in the literature.
