1,4,8,11-Tetraazoniacyclotetradecane tetrachloridocobaltate(II) dichloride

Abstract

The asymmetric unit of the title compound, (C10H28N4)[CoCl4]Cl2, contains two half-molecules of the macrocycle, which are both completed by crystallographic inversion symmetry. In the dianion, the Co2+ cation is tetrahedrally coordinated by four Cl atoms; the Co—Cl bond lengths correlate with the number of hydrogen bonds that the chloride ions accept. The crystal cohesion is supported by electrostatic interactions which, together with numerous N—H...Cl, N—H...(Cl,Cl) and C—H...Cl hydrogen bonds, lead to a three-dimensional network.
