A mixture of 3,5-bis-carboxymethoxy-benzoic acid (0.373 g, 1.50 mmol), Co(CH3COO)2.4H2O (0.282 g, 1.00 mmol), 1,10-phenanthroline (0.049 g, 0.25 mmol), and Na2CO3 (0.079 g, 0.75 mmol) in C2H5OH (2 ml)/H2O (16 ml) was placed in a Teflon-lined stainless steel vessel and heated at 433 K for 72 h, and then cooled to room temperature over 3 days. Then the reaction mixture was filtered and well-shaped pink crystals of compound (I) were obtained from the mother liquor by slow evaporation at room temperature for several days.
The carbon-bound H-atoms were positioned geometrically and included in the refinement using a riding model [aromatic C—H 0.93Å and aliphatic C—H 0.97 Å, Uiso(H) = 1.2Ueq(C)]. The oxygen-bound H-atoms were located in difference Fourier maps and refined with the O—H distance restrained to 0.85 Å and Uiso(H) = 1.2Ueq(O).
Multibenzenecarboxylate ligands, such as terephthalic acid, 1,3,5-benzenetricarboxylic acid, or 1,2,4,5-benzenetetracarboxylic acid, have been employed in the construction of numerous framework compounds (Dai et al., 2002; Rowsell et al., 2005; Wang et al., 2005; Cao et al., 2002). Herein, on the basis of the rigidity of 3,5-dihydroxybenzoic acid, we successfully designed a new multicarboxylate ligand, viz. 3,5-bis-carboxymethoxy-benzoic acid (C11H10O8) (He et al., 2008). In this work, we report the synthesis and structure of a new compound, [Co(C12H8N2)(H2O)4]2[Co(H2O)6](C11H7O8)2.4H2O, (I).
A perspective view of the molecular entities of compound (I) is presented in Fig.1. The asymmetric unit consists of one [Co(C12H8N2)(H2O)4]2+, half a [Co(H2O)6]2+ cation (1 symmetry), one (C11H7O8)23- anion, and two lattice water molecules. In the cations, the CoII atoms show a slightly distorted octahedral coordination (CoO6 and CoO4N2, respectively). In the anion, one of the carboxymethyl groups is almost co-planar to the benzene ring with the dihedral angle of 3.5 (1)°, while the formate group makes a dihedral angle of 17.2 (1)° with the benzene ring. The other carboxymethyl group is almost perpendicular to the benzene ring with the torsion angle C17—O6—C22—C23 of 81.3 (3)°. Together with lattice water molecules, the carboxylic O atoms act as acceptors of O—H···O hydrogen bonds forming a three-dimensional structure (Fig. 2).

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. |

Multibenzenecarboxylate ligands, such as terephthalic acid, 1,3,5-benzenetricarboxylic acid, or 1,2,4,5-benzenetetracarboxylic acid, have been employed in the construction of numerous framework compounds (Dai et al., 2002; Rowsell et al., 2005; Wang et al., 2005; Cao et al., 2002). Herein, on the basis of the rigidity of 3,5-dihydroxybenzoic acid, we successfully designed a new multicarboxylate ligand, viz. 3,5-bis-carboxymethoxy-benzoic acid (C11H10O8) (He et al., 2008). In this work, we report the synthesis and structure of a new compound, [Co(C12H8N2)(H2O)4]2[Co(H2O)6](C11H7O8)2.4H2O, (I).
A perspective view of the molecular entities of compound (I) is presented in Fig.1. The asymmetric unit consists of one [Co(C12H8N2)(H2O)4]2+, half a [Co(H2O)6]2+ cation (1 symmetry), one (C11H7O8)23- anion, and two lattice water molecules. In the cations, the CoII atoms show a slightly distorted octahedral coordination (CoO6 and CoO4N2, respectively). In the anion, one of the carboxymethyl groups is almost co-planar to the benzene ring with the dihedral angle of 3.5 (1)°, while the formate group makes a dihedral angle of 17.2 (1)° with the benzene ring. The other carboxymethyl group is almost perpendicular to the benzene ring with the torsion angle C17—O6—C22—C23 of 81.3 (3)°. Together with lattice water molecules, the carboxylic O atoms act as acceptors of O—H···O hydrogen bonds forming a three-dimensional structure (Fig. 2).
