metal-organic compounds
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—HCl and N—HCl hydrogen bonds. The structure features the formation of inorganic and organic ionic layers, which interpenetrate each other and which are linked by hydrogen bonds.
