(Received 31 October 2007; accepted 2 December 2007; online 12 December 2007)

The title compound, [Mn2(HO3PCH2CH2COO)2(C8H8N2)2(H2O)2], was obtained by hydro­thermal synthesis. The manganese(II) ions are six-coordinate and are linked by two 2-carboxy­ethyl­phospho­nate ligands, forming a centrosymmetric dimer. The Mn ions adopts a distorted octahedral coordination geometry. The dimers are further linked by O—H⋯O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distance 4.2754 (4) Å].

Comment top

In recent years, metal phosphonates have been a rapid expansion research field due to their potential application in the area of catalysis, ion exchange, proton conductivity, intercalation chemistry, photochemistry and materials chemistry (Clearfield 1998). Many metal phosphonates have been reported (Cheetham et al., 1999; Stock et al., 2000; Serpaggi & Férey, 1999; Ying & Mao, 2004; Ying et al., 2006). Metal phosphonates can exhibit various kinds of structures. We report here the crystal structure of a new manganese(II) carboxyalkylphosphonate complex synthesized by the hydrothermal method.

The asymmetric unit of the title compound contains one manganese(II) ion, one doubly deprotonated 2-carboxyethylphosphonic acid ligand, one 2,2'-bipyridine and one coordinated water molecule. The manganese(II) ion is six-coordinated by one phosphonate oxygen atom, one water molecule, two carboxylate oxygen atoms and two N atoms from a 2,2'-bipyridine molecule. The Mn—O distances range from 2.0646 (12) to 2.3161 (14) Å and the Mn—N distances are 2.2437 (16) and 2.2890 (16) Å. Two manganese(II) ions are linked by two 2-carboxyethylphosphonic acid ligands forming a dimer (Fig. 1). The dimers are further interlinked by O—H···O hydrogen bonds and π-π stacking interactions to form a three-dimensional supermolecular structure (Fig. 2). The compound is isostructural with a zinc(II) complex which has been reported recently (Ying et al., 2007).

Experimental top

A mixture of manganese(II) acetate (0.5 mmol, 0.120 g), 2-carboxyethylphosphonic acid (0.5 mmol, 0.076 g), and 2,2'-bipyridine (0.5 mmol, 0.079 g) in 10 ml of distilled water was sealed in an autoclave equipped with a Teflon liner (20 ml) and then heated at 150°C for 3 days. Crystals of the title compound were obtained.

Refinement top

All hydrogen atoms were geometrically positioned with C—H = 0.93–0.98 Å, O—H = 0.82 Å, and refined in the riding-model approximation, with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(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.
