Abstract
The title compound, Ni(C(14)H(16)N(5)O(3))(2) or Ni(ppa)(2), where ppa is 8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxyl-ate, was synthesized under hydro-thermal conditions. The Ni(II) atom (site symmetry ) exhibits a distorted trans-NiN(2)O(4) octa-hedral geometry defined by two monodentate N-bonded and two bidentate O,O'-bonded ppa monoanions. The extended two-dimensional structure is a square grid. An inter-molecular N-H⋯O hydrogen bond occurs.
