2,6-Diaminopyridinium bis(4-hydroxypyridine-2,6-dicarboxylato-[kappa]3O2,N,O6)ferrate(III) dihydrate

Abstract top

The reaction of iron(II) sulfate heptahydrate with the proton-transfer compound (pydaH)(hypydcH) (pyda = pyridine-2,6-diamine; hypydcH2 = 4-hydroxypyridine-2,6-dicarboxylic acid) in an aqueous solution led to the formation of the title compound, (C5H8N3)[Fe(C7H3NO5)2]·2H2O. The anion is a six-coordinated complex with a distorted octahedral geometry around the FeIII atom. Extensive intermolecular O-H...O, N-H...O and C-H...O hydrogen bonds, involving the complex anion, (pydaH)+ counter-ion and two uncoordinated water molecules, and [pi]-[pi] [centroid-to-centroid distance 3.323 (11) Å] and C-O...[pi] [O-centroid distance 3.150 (15) Å] interactions connect the various components into a supramolecular structure.

Comment top

Noncovalent interactions including hydrogen bonding, ion pairing, hydrophobic or hydrophilic and donor–acceptor interactions play a key role in chemical, catalytic and biochemical processes, as well as supramolecular chemistry and crystal engineering. Our research group has recently focused on synthesis of water soluble self-assembly systems that can function as suitable ligands in the synthesis of metal complexes. We have reported some complexes with pyridinedicarboxylic acids (Rafizadeh et al., 2004, 2006, 2007a,b; Rafizadeh & Amani, 2006).

In the title compound (Fig. 1), the FeIII atom has a distorted octahedral geometry. The bond angles (Table 1) and the torsion angles O6—Fe1—O1—C1 [100.80 (13)°], O1—Fe1—O6—C8 [103.59 (13)°], O8—Fe1—O3—C7 [104.38 (13)°] and O3—Fe1—O8—C14 [106.46 (14)°] indicate that two dianionic hypydc ligands are almost perpendicular to each other. In this work we used FeII ions as starting material. Most probably during the synthesis process, FeII was oxidized into FeIII. There are a large number of O—H···O, N—H···O and C—H···O hydrogen bonds between the cations, anions and water molecules (Table 2). Considerable π–π interaction [centroid–centroid distance = 3.323 (11) Å] between the cation and anion, and C—O···π interaction [O–centroid distance = 3.150 (15) Å] between two anions are observed (Fig. 2). Hydrogen bonds, π–π and C—O···π interactions result in the formation of a supramolecular structure (Fig. 3).

Experimental top

The reaction of FeSO4.7H2O (0.139 g, 0.5 mmol) in water (20 ml) with (pydaH)(hypydcH) (0.264 g, 1.0 mmol) in water (20 ml) gave colorless crystal of the title compound. Crystals suitable for X-ray diffraction were obtained by slow evaporation of the solvent at room temperature.

Refinement top

H atoms attached to O and N atoms and water molecules are located from difference Fourier maps and refined isotropically with their coordinates fixed. H atoms on C atoms were positioned geometrically and refined in riding model, with C—H = 0.95 Å and Uiso(H) = 1.2Ueq(C).

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.
