Poly[[bis­[μ(2)-8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro­pyrido[2,3-d]pyrimidine-6-carboxyl­ato]cobalt(II)] dihydrate]

The title compound, {[Co(C(14)H(16)N(5)O(3))(2)]·2H(2)O}(n) or [Co(ppa)(2)]·2H(2)O}(n), where ppa denotes the 8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro­pyrido[2,3-d]pyrimidine-6-carb­ox­yl­ate anion, was synthesized under hydro­thermal conditions. The Co(II) atom (site symmetry [Image: see text])...

description The title compound, {[Co(C(14)H(16)N(5)O(3))(2)]·2H(2)O}(n) or [Co(ppa)(2)]·2H(2)O}(n), where ppa denotes the 8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro­pyrido[2,3-d]pyrimidine-6-carb­ox­yl­ate anion, was synthesized under hydro­thermal conditions. The Co(II) atom (site symmetry [Image: see text]) exhibits a distorted trans-CoN(2)O(4) octa­hedral geometry defined by two monodentate N-bonded and two bidentate O,O′-bonded ppa anions. The extended two-dimensional structure is a square grid, which is consolidated by N—H⋯O hydrogen bonds. The disordered uncoordinated water mol­ecules occupy cavities within the grid.
