Bis(triethylammonium) tetrachloridocobaltate(II)

Abstract

The crystal structure of the title compound, (C6H16N)2[CoCl4], is comprised of a tetrahedral [CoCl4]2− anion and two independent triethylammonium cations. The latter are featureless while the [CoCl4]2− anion exhibits typical Co—Cl bond lengths [2.2428 (15)–2.2847 (16) Å] and a Cl—Co—Cl angular range of 107.58 (6)–112.73 (7)°. In the crystal, N—H...Cl hydrogen bonds between the two crystallographically independent cations and the [CoCl4]2− anion generate discrete ion triplets. The two Co—Cl bonds involved in these interactions are slightly longer than the remaining two.
