Diaqua­bis­[1,2-bis­(pyridin-4-yl)ethene]­bis­[2-(4-carboxy­phen­yl)acetato]­cobalt(II)

The asymmetric unit of the title compound, [Co(C(9)H(7)O(4))(2)(C(12)H(10)N(2))(2)(H(2)O)(2)], consists of one Co(2+) ion, one mono-deprotonated 2-(4-carboxyl­atophen­yl)acetate carboxylic acid, one 1,2-bis­(pyridin-4-yl)ethane mol­ecule and one water mol­ecule. The Co(II) atom is situated on a crystallographic center of inversion and is octa­hedrally coordinated by two O atoms from two anions, two N atoms of two 1,2-bis­(pyridin-4-yl)ethane mol­ecules and two O atoms from two water mol­ecules. A three-dimensional network is established by inter­molecular O—H⋯O and O—H⋯N hydrogen bonds.
