Crystal structure of di-μ(2)-chlorido-bis­[(1-aza-4-azoniabi­cyclo­[2.2.2]octane-κN (1))di­chlorido­dicadmium]

In the structure of the binuclear title compound, [Cd(2)(C(6)H(13)N(2))(2)Cl(6)], two Cd(II) atoms are bridged by two Cl(−) ligands, defining a centrosymmetric Cd(2)Cl(2) motif. Each metal cation is additionally coordinated by two Cl(−) ligands and the N atom of a protonated 1,4-di­aza­bicyclo­[2.2.2]octane (H-DABCO)(+) ligand, leading to an overall trigonal–bipyramidal coordination environment with one of the bridging Cl(−) ligands and the N atom at the apical sites. In the crystal, the neutral dimers are linked via N—H⋯Cl hydrogen bonds, forming a two-dimensional network expanding parallel to (100).
