description The title layered coordination polymer, [Cd(C(14)H(16)N(5)O(3))(2)](n) or [Cd(ppa)(2)](n), where ppa is 8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro­pyrido[2,3-d]pyrimidine-6-carboxyl­ate, was syn­thesized under hydro­thermal conditions. The Cd(II) atom (site symmetry 2) exhibits a distorted cis-CdN(2)O(4) octa­hedral geometry defined by two N-monodentate and two O,O′-bidentate ppa monoanions. The extended two-dimensional structure resulting from the bridging ppa species is a grid lying parallel to (001). An N—H⋯O hydrogen bond helps to establish the crystal packing.
