Poly[tetraaquabis(-hydrogen maleato)barium(II)]

J.-L. Zheng and S.-K. Lin

Abstract: In the title compound, [Ba(C₄H₃O₄)₂(H₂O)₄]_n, the barium(II) cation is coordinated by five O atoms from four different hydrogen maleate ions and four O atoms from water molecules in a tricapped trigonal prismatic geometry. The coordination polyhedra are connected by edge-sharing to form zigzag chains, which are linked by hydrogen bonds into an extended three-dimensional network.
