Popis: | The title compound, {[Zn(C14H16N5O3)2]·2H2O}n or [Zn(ppa)2]·2H2O}n, where ppa = 8-ethyl-5,8-dihydro-5-oxo-2-(1-piperazinyl)-pyrido(2,3-d)-pyrimidine-6-carboxylate, was synthesized under hydrothermal conditions. The ZnII atom (site symmetry overline{1}) exhibits a distorted trans-ZnN2O4 octahedral geometry defined by two monodentate N-bonded and two bidentate O,O-bonded ppa monoanions. The extended two-dimensional structure arising from this connectivity is a square grid and the disordered uncoordinated water molecules occupy cavities within the grid. An N—H...O hydrogen bond occurs. |
