RESUMO
In the title compound, C(9)H(11)N(3)O, the crystal structure is stabilized by a bifurcated inter-molecular N-Hâ¯(N,O) hydrogen bond and a C-Hâ¯O inter-action, leading to chains of mol-ecules.

RESUMO
In the title compound, {[Cu(C(16)H(17)FN(3)O(3))(2)]·4H(2)O}(n), the Cu(II) atom is bonded to two O,O'-bidentate 1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydro-quinoline-3-carboxyl-ate (norf) monoanions and a symmetry-generated N-bonded norf anion, resulting in a distorted square-pyramidal coordination environ-ment with the N atom occupying the apical site. The bridging norf anion results in one-dimensional chains propogating along [010]. A network of O-Hâ¯O and N-Hâ¯O hydrogen bonds helps to establish the crystal structure.
