Crystal structure of di-μ2-chlorido-bis-[(1-aza-4-azoniabi-cyclo-[2.2.2]octane-κN (1))di-chlorido-dicadmium]

In the structure of the binuclear title compound, [Cd₂(C₆H₁₃N₂)₂Cl₆], two Cd^II atoms are bridged by two Cl⁻ ligands, defining a centrosymmetric Cd₂Cl₂ 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).
