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-piperazin-yl)-pyrido(2,3-d)-pyrimidine-6-carboxyl-ate, was synthesized under hydro-thermal conditions. The Zn(II) atom (site symmetry ) exhibits a distorted trans-ZnN(2)O(4) octa-hedral geometry defined by two monodentate(More)
