In the title three-dimensional coordination polymer, {[Fe(C8H5NO4)(H2O)]·2H2O}n, the FeII atom exhibits a distorted octa­hedral geometry, being coordinated by one N and four O atoms from four 5-amino­isophthalate ligands and one water mol­ecule. In addition, the crystal structure is stabilized by numerous O—H⋯O and N—H⋯O hydrogen bonds.

Comment top

5-Aminoisophthalatic acid is a good example of a bridging ligand that can link metal centres into extended networks, and a number of one-, two- and three- dimensional coordination frameworks have been generated (Zeng et al., 2007; Wu et al., 2002; Liao et al. 2006). Recently, we have obtained the title three-dimensional iron polymer, (I), and its crystal structure is reported here. This complex is isostructural with the MnII complex reported by Liao and Yao (2006) and by Li et al. (2006).

In the structure of (I) each FeII atom is coordinated by four O atoms from three 5-aminoisophthalate ligands, one N atom from another 5-aminoisophthalate ligand and one water molecule, and displays a distorted octahedral coordination geometry. The 5-aminoisophthalate ligands bridge iron ions to form a three-dimensional network (Fig. 2). Moreover, there are O—H···O and N—H···O hydrogen-bonding interactions within the three-dimensional structure connecting the carboxyl O atoms and amino N atoms of 5-aminoisophthalate ligands, the coordinating water molecules and water of crystallization (Table 2).

Experimental top

A mixture of FeCl2 (0.5 mmol), 5-aminoisophthalatic acid (0.5 mmol), NaOH (1 mmol) and H2O (12 ml) was placed in a 23 ml Teflon reactor, which was heated at 433 K for three days and then cooled to room temperature at a rate of 5 K h-1. Single crystals were obtained after washing with water and drying in air.

Refinement top

All H atoms attached to C and N atoms were fixed geometrically and treated as riding on their parent atoms with C—H = 0.93 Å (aromatic), N—H = 0.90 Å and Uiso(H) = 1.2 Ueq(C,N). H atoms from water molecules were located in difference Fourier maps and included in the subsequent refinement using restraints [O—H= 0.82 (1) Å and H···H= 1.34 (2) Å] with Uiso(H) = 1.5Ueq(O).

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.
