The crystal structure of the title compound, (C(12)H(30)N(2))[CoCl(4)], is composed of discrete (C(12)H(30)N(2))(2+) cations and [CoCl(4)](2-) anions. The asymmetric unit contains a half-cation and a half-anion. The atoms of the cation occupy general positions about an inversion centre, which is located at the midpoint of the central C-C bond. The Co atoms lie on a twofold rotation axis. The slightly distorted tetra-hedral coordination environment around the metal atom consists of two Cl atoms and their symmetry-related pairs.
