The title compound, {[Zn(C(14)H(16)N(5)O(3))(2)]·2H(2)O}(n) or [Zn(ppa)(2)]·2H(2)O}(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 Zn(II) atom (site symmetry [Image: see text]) exhibits a disto...

description The title compound, {[Zn(C(14)H(16)N(5)O(3))(2)]·2H(2)O}(n) or [Zn(ppa)(2)]·2H(2)O}(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 Zn(II) atom (site symmetry [Image: see text]) exhibits a distorted trans-ZnN(2)O(4) 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.
