O1)[8-ethyl-5-oxo-2-(piperazin-4-ium-1-yl)-5,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylato-
2O5,O6]zinc monohydrateIn the title compound, [Zn(C14H17N5O3)(C9H4O6)(H2O)2]·H2O, the complex molecule exists in a zwitterionic form. The ZnII ion exhibits a distorted tetragonal-pyramidal geometry, being coordinated by two O atoms from the zwitterionic 8-ethyl-5-oxo-2-(piperazin-4-ium-1-yl)-5,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylate (L) ligand, one O atom from the 5-carboxybenzene-1,3-dicarboxylate dianion, [Hbtc]2-, and two O atoms from two aqua ligands. In the crystal, N-H
O and O-H
O hydrogen bonds link the components into a three-dimensional structure. The crystal packing exhibits
-
interactions between the aromatic rings, with centroid-centroid distances in the range 3.466 (3)-3.667 (3) Å.
A mixture of Zn(OAC)2.3H2O (0.546 g, 0.25 mmol), L (0.758 g, 0.25 mmol), H3btc(0.526 g, 0.25 mmol) and distilled water (8 mL) was stirred for 20 min in air. The mixture was then transferred to a 23 ml Teflon-lined hydrothermal bomb. The bomb was kept at 423 K for 96 h under autogenous pressure. Upon cooling, colorless block of 1 was obtained from the reaction mixture.
C-bound H atoms were positioned geometrically [C—H = 0.97 Å] and refined using a riding model approximation, with Uiso(H) = 1.2 – 1.5 Ueq(C). The N- and O-bound H atoms were located on a difference Fourier map, but placed in idealized positions [N—H = 0.90 Å, O—H = 0.82-0.85 Å] and refined as riding, with Uiso(H) =1.2 Ueq of the parent atom.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Pipemidic acid (8-ethyl-5-oxo-2-piperazin-1-yl-5,8-dihydropyrido[2,3-d]pyrimidine-6- carboxylic acid), L, is a member of quinolones used to treat various infections (Mizuki et al., 1996). The complexes of the L ligand and [Hbtc]2- anion have not been reported till now. In this paper, we report the crystal structure of the title compound.
The asymmetric unit of the title compound is composed of one ZnII ion, one L ligand , one [Hbtc]2- anion (H3btc = benzene-1,3,5-tricarboxylic acid), two coordinated and one lattice water molecules (Fig. 1). All bond lengths in L are normal, though slightly different from those reported for base molecule L earlier by Zhang et al. (2011). So, the C1—O2, C3—O3 and C1—O1 bond lengths are 1.255 (2), 1.275 (2) and 1.255 (2) Å, respectively, versus 1.219 (2), 1.268 (3) and 1.319 (3) Å reported by Zhang et al. (2011).
In the crystal, intermolecular N—H···O and O—H···O hydrogen bonds (Table 1) link all moieties into three-dimensional supramolecular structure. The crystal packing exhibits π–π interactions between the aromatic rings with the intercentroids distances covering the range 3.466 (3) – 3.667 (3) Å.
