title: Poly[di-μ(2)-acetato-diaquabis(2,2'-bi-pyridine)bis(μ(3)-5-nitroisophthalato)tricobalt(II)].
abstract: The title complex, [Co(3)(C(8)H(3)NO(6))(2)(C(2)H(3)O(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], was synthesized under hydro-thermal conditions. The structure features a centrosymmetric complex with three Co(II) centres, one of which is located on a centre of inversion. The Co centres are coordinated in a distorted octa-hedral geometry. The bipyridine ligands are bonded to just one Co centre in a chelating mode, whereas the 5-nitro-isophthalate and acetate ions are bonded to two different Co atoms. The crystal structure is stabilized by O-H⋯O hydrogen bonds.
