title: 1,4,8,11-Tetra-azoniacyclo-tetra-decane tetra-chloridocobaltate(II) dichloride.
abstract: The asymmetric unit of the title compound, (C(10)H(28)N(4))[CoCl(4)]Cl(2), contains two half-mol-ecules of the macrocycle, which are both completed by crystallographic inversion symmetry. In the dianion, the Co(2+) cation is tetra-hedrally 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 inter-actions which, together with numerous N-H⋯Cl, N-H⋯(Cl,Cl) and C-H⋯Cl hydrogen bonds, lead to a three-dimensional network.
