Poly[[bis[μ2-8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylato]cobalt(II)] dihydrate]

The title compound, {[Co(C14H16N5O3)2]·2H2O}n or [Co(ppa)2]·2H2O}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 CoII atom (site symmetry overline{1}) exhibi...
