| Summary: | The title layered coordination polymer, [Cd(C14H16N5O3)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 CdII atom (site symmetry 2) exhibits a distorted cis-CdN2O4 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. |
