Bis(triethylammonium) tetrachlorido-cobaltate(II)

Abstract

The crystal structure of the title compound, (C6H 16N)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.
