Bis(piperazinium) di-μ-chloro-bis[diaquadichloromanganate(II)] dichloride

The title compound, (C4H12N2)2[Mn2Cl6(H2O)4]Cl2, consists of two piperazinium cations, two chloride anions and a dimanganese complex anion, which lies on a center of symmetry. Each MnII atom is located in a distorted octa­hedral environment. The cations and the anions are held together by O—H⋯Cl and N—H⋯Cl hydrogen bonds. The structure features the formation of inorganic and organic ionic layers, which interpenetrate each other and which are linked by hydrogen bonds.
