The title complex, [Co(C10H9O5)2(C10H10O5)2(C5H5N)2], is a neutral mononuclear complex. The CoII atom, which lies on a centre of symmetry, has a distorted octa­hedral geometry involving two O atoms of the 3-(4-carboxy­phen­oxy)propionate groups, two O atoms of the 3-(4-carboxy­phen­oxy)propionic acid groups and two N atoms of two pyridine ligands. A two-dimensional supra­molecular structure is constructed via π–π inter­actions [centroid-to-centroid distance 3.589 (3) Å] and hydrogen-bonding inter­actions.

Comment top

Our studies have addressed the metal derivatives of carboxyphenoxypropionic acids. 3-(4-carboxylatophenoxy)propionic acid [3-(p-CPOPH2)] is a potential flexible multidentated ligand which could be used as a terminal ligand or a bridging ligand with different coordination modes when coordinated to various metal ions. In addition to its versatile coordination modes, 3-(4-carboxylatophenoxy)propionic acid may take part in hydrogen-bonding interactions by functioning as either a hydrogen-bond donor or acceptor (Gao & Ng, 2006). Recently, we have reported the structure of a dinuclear cobalt(II) complex incorporating 3-(4-carboxylatophenoxy)propionate groups, namely [Co2(C10H8O5)2(H2O)8].4H2O, (I) (Xiao et al., 2006).

In contrast to (I), the title compound is a mononuclear complex (Fig. 1), in which the Co atom lies on a centre of symmetry and displays a distorted octahedral geometry involving two O atoms of the 3-(4-carboxylatophenoxy)propionate groups, two O atoms of the 3-(4-carboxyphenoxy)propionic acid groups and two N atoms of two pyridine ligands. The average Co—O(carbonyl) bond length is 2.094 (2) Å, which is somewhat longer than the corresponding value in (I), 2.038 (3) Å. Furthermore, a two-dimensional supramolecular layer is constructed via ππ stacking interactions between the pyridine rings [centroid-centroid distance: 3.589 (3) Å] and hydrogen-bonding interactions (Table 2). There is, in additiom, a strong intramolecular H-bond (first entry in Table 2 and Fig. 1), linking the two independent, coordinated carboxylate groups.

3-(4-Carboxyphenoxy)propionic acid [3-(p-CPOPH2)] has been reported previously (Gao & Ng, 2006). In our previous work, the cobalt(II) complex of 3-(p-CPOPH2) has been characterized by X-ray crystallography (Xiao et al., 2006).

Experimental top

The title complex was prepared by the addition of cobalt(II) acetate trihydrate (10 mmol), pyridine (1 ml) and 3-(p-CPOPH2) (15 mmol) to a H2O/MeOH (v/v = 1:1) solution. Red crystals were obtained from the filtered solution at room temperature over several days. CH&N analysis. Calc. for C50H48N2O20Co: C 56.88, H 4.58, N 2.65%. Found: C 56.89, H 4.56, N 2.66%.

Refinement top

The H atoms were placed in calculated positions with C—H = 0.93 or 0.97 Å and Uiso(H) = 1.2Ueq (C) and were included in the refinement in the riding model approximation. The H atoms of hydroxyl groups were located in difference Fourier maps and refined with the O—H distance restrained to 0.85 (1) Å and Uiso(H) = 1.5Ueq(O).

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.

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.
