metal-organic compounds
In the crystal structure of the title compound, [Mn(C10H14O4)(C12H8N2)(H2O)2]·3H2O, the MnII atom is in a distorted octahedral geometry, being coordinated by two N atoms of one 1,10-phenanthroline ligand, two O atoms from two carboxylate groups of the chelating cyclohexane-1,1′-diacetate dianion and two O atoms of two trans water molecules. The complex molecules are linked to form a three-dimensional network by hydrogen-bonding interactions between coordinated water molecules, non-coordinated water molecules and carboxylate groups of neighbouring molecules, and by aromatic π–π stacking interactions of the phenthroline rings.
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.
