In the dinuclear title complex, [Fe2(OH)2(C7H3NO4)2(H2O)2]·H2O, the two Fe atoms are separated by 3.063 (1) Å. Inter­molecular O—H⋯O hydrogen bonds form an extensive three-dimensional hydrogen-bonding network, which consolidates the crystal packing.

Comment top

In continuation of our structural study of coordination compounds bearing different dicaroxylic acid and amine base fragments via proton transfer methodology (Aghabozorg et al., 2008 and references therein; Eshtiagh-Hosseini et al. 2010), we present here the title compound, (I). The crystal structure of anhydrous form of I already has been reported by Thich et al. (1976); [(pydc)H2OFeOH]2 (II). The considerable feature of the title compound, is that the basic properties of (pydc)2- did not allow 5-bromo-6-methyl-2-(4-methylpiperazine-1-yl)pyrimidine-4-amine (bmpa) participitate in the crystalline network. The other interesting point is that two FeIII ions have different chemical environment making them non equivalent but with similar coordination geometry, that is, each FeIII ion is hexa-coordinated by one tridentate (pydc)2-, two µ-hydroxo, and one coordinated water molecule (Fig. 1).

The above-mentioned complexes are very similar in terms of molecular structure but with different crystal structures. Both structures consist of [(pydc)H2OFe(OH)]2 dimeric units but the only difference between them is the peresence of a crystalline water molecule in the I.

In I (Fig. 1), all bond lengths and angles are normal and comparable with those observed in anhydrous form of the title dinuclear complex (Thich et al., 1976). In the crystal structure, intermolecular O—H···O hydrogen bonds (Table 1) form an extensive three-dimensional hydrogen-bonding network, which consolidate the crystal packing. Indeed, firstly, covalent bonds cause to constructe dinuclear skeleton, and then the classical hydrogen bond interactions caused by O—H···O, lead to the self-aggregation process.

Experimental top

A solution of FeCl3.6H2O was added to a mixture of pydcH2 and bmpa in molar ratios of 1:2:2, respectively. The obtained solution was refluxed for 6 hrs in the 343 K. Suitable orange chunk [(µ-OH)2Fe2(pydc)2(H2O)2].H2O crystals for single crystal X-ray structure determination were obtained after slow evaporation of solvent in R.T.

Refinement top

C-bound H atoms were geometrically positioned (C—H 0.93 Å) and refined as riding, with Uiso(H)=1.2Ueq(C). O-bound H atoms were located on a difference map and isotropically refined.

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. Outlier data were removed using a local program based on the method of Prince and Nicholson [Prince, E. & Nicholson, W. L. (1983). Acta Cryst. A39, 407–410.]

Refinement on F2 for ALL reflections except for 0 with very negative F2 or flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating R_factor_obs 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.
