Di-μ-chlorido-bis[bis(ethylenediamine-κ2N,N′)cadmium(II)] dichloride

The crystal structure of the title compound, [Cd2Cl2(C2H8N2)4]Cl2, consists of binuclear centrosymmetric [Cd2(C2H8N2)4Cl2]2+ cations and discrete chloride anions. The CdII cation is coordinated by four N atoms of two ethylenediamine ligands and two symmetry-related chloride anions within a distorted CdN4Cl2 octahedron. Two CdII cations are connected by two chloride anions via μ2-coordination, forming a four-membered Cd2Cl2 ring. The uncoordinated chloride anions are linked to the amino groups via N—H...Cl hydrogen bonding. Two C atoms of one of the two crystallographically independent ethylenediamine ligands are disordered and were refined using a split model [occupancy ratio 0.674 (9):0.326 (9)].
