Poly[[triaqua­[μ4-N-(4-carboxyl­ato­phenyl)­iminodiacetato]sodium(I)zinc(II)] dihydrate]

Abstract

In the title coordination polymer, {[NaZn(C11H8NO6)(H2O)3]·2H2O}n, the Zn atom is coordinated in a distorted tetra­hedral environment by three carboxyl­ate O atoms from two (4-carboxyl­atophenyl­imino)diacetate ligands and one water mol­ecule; the Na atom is in an distorted octa­hedral coordination environment formed by four carboxyl­ate O atoms from three (4-carboxyl­atophenyl­imino)diacetate ligands and two water mol­ecules. The Zn atoms and Na atoms are linked by (4-carboxyl­atophenyl­imino)diacetate ligands into a three-dimensional framework; the uncoordinated water mol­ecules fill the voids of the skeleton and stabilize it by O—H(...)O hydrogen bonds.

Comment

2,2'-(4-Carboxyphenylazanediyl)diacetic acid is a multidentate flexible ligand with versatile binding abilities and capability of participating in hydrongen bonds, thus representing an excellent candidate for the construction of supramolecular complexe. In this paper, we report a novel title compound, (I), which is prepared by 2,2'-(4-carboxyphenylazanediyl)diacetic acid ligand and Zinc dinitrate under neutral aqueous conditions, which forms a three-dimensional framework structure.

The asymmetric unit of (1) consists of one Zn(II) ion, one Na(I) ion, one 4-carboxylatophenylimino)diacetate anion, three coordinated water molecules and two uncoordinated water molecules (Fig. 1). The Zn(II) ion is in a tetrahedral coordination environment, formed by three carboxylate O atoms from two 4-carboxylatophenylimino)diacetate ligands and one water molecules. The Na(I) ion exists in a distorted octahedral configuration with the equatorial plane being defined by the atoms O1, O2, O4II and O8, and with O9 and o4III occupy the axial sites. Each 4-carboxylatophenylimino)diacetate anion bridged two Zn(II) ions and three Na(I) ions to form a three-dimensional supramolecular framework network in which uncoordinated water molecules filled the space of the skelecton and stabilized by O—H···O hydrogen bonds(Fig. 2, Table 1).

Experimental

2,2'-(4-Carboxyphenylazanediyl)diacetic acid was synthesized by the literature method (Young et al., 1958). The complex (I) was synthesized with znic(II) dinitrate (0.375 g, 2 mmol) and 2,2'-(4-Carboxyphenylazanediyl)diacetic acid (0.253 g, 1 mmol) were dissolved in methanol and the pH was adjusted to about 7 with 0.01M sodium hydroxide. Colorless crystals were separated from the filtered solution after several days.

Refinement

H atoms bound to C atoms were placed in calculated positions and treated as riding on their parent atoms, with C—H = 0.93 Å, 0.97 Å for aromatic and methylene H atoms respectively; Uiso(H) was set to = 1.2Ueq of the carrier atom. Water H atoms were placed in calculated positions, with O—H=0.85 Å, Uiso(H) = 1.Ueq(O).

Special details

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.
