Abstract top

The polymeric title compound, {(C4H12N2)[Zn(C7H3NO4)2(H2O)]·2H2O}n, was obtained by the reaction of zinc(II) nitrate hexahydrate with the proton-transfer compound (pipzH2)(py-2,5-dc) (where pipz is piperazine and py-2,5-dcH2 is pyridine-2,5-dicarboxylic acid) in aqueous solution. Each ZnII atom is coordinated in a distorted octahedral geometry by four O atoms and two N atoms from one water molecule and two (py-2,5-dc)2- ligands, which also act as bridging ligands between ZnII atoms. [pi]-[pi] Stacking interactions between two aromatic rings of (py-2,5-dc)2- fragments, with centroid-centroid distances of 3.4747 (7) and 3.7081 (7) Å are observed. The crystal structure is stabilized by O-H...O and N-H...O hydrogen bonds.

Comment top

Our research group has recently focused on one-pot synthesis of water soluble self-assembly systems that can function as suitable ligands in the synthesis of metal complexes (Aghabozorg et al., 2007, 2007a, 2007b).

The molecular structure of the title compound is shown in Fig. 1. The negative charge of the anionic complex is neutralized by dicationic piperazinediium species.

The ZnII atom is hexacoordinated by two nitrogen atoms, two O atoms from carboxylate groups of two (py-2,5-dc)2– fragments, one O atom from a bridging (py-2,5-dc)2– ligand and one O atom from a coordinated water molecule. O7 and O9 atoms occupy the axial positions, while N1, N2, O1 and O5 atoms form the equatorial plane. The O9—Zn1—O7i (i: -x + 1, y - 1/2, -z + 1/2) bond angle revealed ~7.6° deviation from linearity. There are two uncoordinated water molecules and one piperazinediium ion as counter-ion, with some hydrogen bonds to water molecules and coordinated COO- groups of (py-2,5-dc)2– fragments.

The (py-2,5-dc)2– fragments are bridging via carboxylate group, connecting the ZnII atoms together into a layered structure in which the space between the [Zn(H2O)(py-2,5-dc)2]2– species is filled by piperazinediium ions and water molecules (Fig. 2).

The dihedral angle between the aromatic rings of (py-2,5-dc)2– groups connected to the same Zn atom is 6.82 (6)°, indicating that these fragments are almost coparallel.

π-π stacking interactions between two aromatic rings of (py-2,5-dc)2–, with centroid-centroid distances of 3.4747 (7) Å (symmetry code: -x, 1/2 + y, 1/2 - z) and 3.7081 (7) Å (symmetry code: -x, -1 - y, -z) are observed in the title compound (Fig. 3).

Experimental top

The proton transfer compound was prepared by a reaction between piperazineand pyridine-2,5-dicarboxylicacid (Sheshmani, et al., 2007). A solution of Zn(NO3)2.6H2O (130 mg, 0.5 mmol) in water (15 ml) was added to an aqueous solution of (pipzH2)(py-2,5-dc) (253 mg, 1.0 mmol) in water (15 ml) in a 1:2 molar ratio. Colorless crystals were obtained after a few days at room temperature.

Refinement top

The hydrogen atoms of NH2 groups and water molecules were found in difference Fourier synthesis. Nevertheless, all hydrogen atoms were refined using a riding model with with the Uiso(H) parameters equal to 1.2 Ueq(C,N,O) and Caromatic—H = 0.95 Å, Cmethylene—H = 0.99 Å, O—H = 0.82Å and N—H = 0.92 Å.

Special details top

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.
