In the title compound, [NaZn(C9H3O6)(H2O)4]n, the ZnII atom is six-coordinated by four O atoms from two different benzene-1,3,5-tricarboxylate anions and two water O atoms in a distorted tetragonal-bipyramidal geometry and the NaI atom is five-coordinated by three O atoms from three different benzene-1,3,5-tricarboxylate anions and two water O atoms in a distorted trigonal-bipyramidal geometry. The benzene-1,3,5-tricarboxylate anion bridges two ZnII atoms and two NaI atoms, resulting in the formation of a two-dimensional layer structure. Intermolecular O—H⋯O hydrogen-bonding interactions generate a three-dimensional superamolecular structure.

The mixture of of benzene-1,3,5-tricarboxylate acid (0.063 g, 0.3 mmol), NaOH (0.024 g, 0.25 mmol), Zn(Ac)2 (0.066 g, 0.3 mmol), and 10 ml H2O was sealed in 18 ml Teflon-lined stainless steel container. The container was heated to 150 °C and held at that temperature for 72 h, then cooled to room temperature at a rate of 10 °C.h-1. And then crystals of the title compound were isolated.
C-bound H-atoms were geometrically positioned (C—H = 0.93 Å) and refined using a riding model, with Uiso(H) = 1.2Ueq (C). The H atoms of the water molecules were located in a difference map, and were refined with distance restraints of O—H = 0.85 Å.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

In the title compound, (I), each ZnII cation is six-coordinated by five O atoms from two different benzene-1,3,5-tricarboxylate anions and two water molecules. The Zn—O (carboxylate) distance in I is similar to the equivalent value in a related compounds (Majumder et al. 2005). Each NaI cation is five coordinated by three oxygen atoms from three different benzene-1,3,5-tricarboxylate anions and two water molecules. The Na—O (carboxylate) distance is similar to the related compounds (Chui et al. 1999) (Fig. 1). The ZnII centers and the NaI centers are bridged by benzene-1,3,5-tricarboxylate anions, resulting in a two dimensional layer (Fig. 2). In (I), there are intra and intermolecular O-H···O hydrogen bonds involving the water molecules and the oxygen atoms of the carboxylate groups (Table 1). The adjacent layers are bridged by the hydrogen bonds, and the whole structure displays a three dimensional supramolecular framework (Fig. 3).
