title: Poly[tetra-mu-aqua-hexaaquadi-mu3-malonato-dinitratodibarium(II)nickel(II)].
abstract: The title complex, [Ba2Ni(C3H2O4)2(NO3)2(H2O)10]n, has a two-dimensional layer structure. The Ni atom lies on a crystallographic centre of symmetry in an octahedral NiO6 environment, and is coordinated by four malonate O atoms in a planar arrangement and by two water molecules in axial positions. The coordination of the unique Ba atom involves two nitrate O atoms, five water molecules and three malonate O atoms.
