Structural study of [(CH3)2NH2]2CoCl4 single crystals at room temperature

The structure of the crystals grown from a solution of dimethylammonium and cobalt chlorides is determined. It is found that the crystals have the composition [(CH3)2NH2]2CoCl4. At room temperature, the crystals are monoclinic (space group P21/c, Z = 4) and the unit cell parameters are as follows: a = 8.545(2) A, b = 11.447(2) A, c = 13.313(3) A, and β = 90.10°. Cations and anions form simple and bifurcated hydrogen bonds N-H⋯Cl.
