Tetramethylammonium tetraaquadichlorochromium(III) trichloride dihydrate

Journal article, 2004

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- ions and water molecules in between the 'bricks'. The structure is compared with aquapentachlorochromate(III) complexes in the literature.
