Abstract The title compound [BaCo(C3H2O4)2(H2O)4] was synthesized and its crystal structure was determined. The compound is orthorhombic, space group Pccn with a = 18.974(3) Å, b = 6.783(2) Å, c = 9.394(4) Å. The structure is polymeric and consists of edge-sharing BaO8 polyhedra and CoO6 octahedra linked together by the malonate groups. The geometry around the Ba(II) centres is a slightly distorted square-antiprism with Ba–O distances ranging from 2.789(4) to 2.843(4) Å. Around the Co(II) centres, the coordination forms a distorted octahedron with Co–O bonds between 2.040(3) and 2.238(4) Å. |
