The title complex, [Co2(C8H5NO4S)2(C10H8N2)3(H2O)2]·1.3H2O, was synthesized under hydrothermal conditions. The CoII ion is six-coordinated in a slightly distorted octahedral environment resulting from two carboxylate O atoms of two 2-carboxymethylsulfanyl nicotinate (2-CMSN2−) anions, one water molecule and three N atoms of three 4,4′-bipyridine ligands, with one 4,4′-bipyridine ligand situated on a centre of inversion. Two neighboring CoII ions are linked by two anions, giving a dinuclear [Co2(2-CMSN)2] subunit with a Co⋯Co separation of 6.8600 (3) Å. The dinuclear subunits are joined by bridging 4,4′-bipyridine linkers, generating a three-dimensional network structure. Disordered water molecules are situated in the free space of this network. O—H⋯O hydrogen bonding within and between the subunits enhances the stability of the structure.

A mixture of 2-H2CMSN (0.4 mmol, 0.086 g), CoCl2 (0.4 mmol, 0.095 g) and 4,4'-bipy (0.4 mmol, 0.062 g) in CH3CH2OH (2 ml)/H2O (18 ml) was stirred for 1 h. The pH value was adjusted to around 6.0 by sodium carbonate solution in the entire process. Then the mixture was placed in a 25 ml stainless steel reactor and heated at 383 K for 24 h, and then cooled to room temperature for 24 h gave red crystals (yield 46%).
The carbon-bound H-atoms were placed in idealized positions [(C—H = 0.93 or 0.97 Å, Uiso(H) = 1.2Ueq(C)]. The coordinating water H-atoms were located in a different Fourier map and were refined with an O—H distance restrained to 0.85 (2) Å [Uiso(H) = 1.2Ueq(O)]. The two lattice water molecules are occupationally disordered (occupancies of 0.4 for OW2 and 0.25 for OW3). No reasonable H positions could be determined from Fourier maps for these atoms. Therefore the H atoms of OW2 and OW3 were omitted from
but included in the final chemical formula.The construction of coordination polymers has aroused attention due to their potential applications, fascinating topologies and entanglement motifs (Wang et al., 2004).
2-Mercaptonanicotinic acid (2-H2MN) is a multifunctional ligand containing one carboxyl group, one thiol group and a pyridyl N donor atom. Some complexes based on the 2-MN2- ligand have been previously investigated, e.g. by Sun et al. (2011). Recently, on the basis of the 2-H2MN ligand, we have designed a new multi-carboxylate ligand, 2-carboxymethylsulfanyl nicotinic acid (2-H2CMSN) to construct novel complexes (Jiang et al., 2010; 2012). The 2-H2CMSN ligand is interesting because of its potential versatile coordination behavior, resulting from one rigid and one flexible carboxyl group. Due to the flexible carboxyl group, it is favorable for constructing novel network structures. Here we report the structure of the new title compound, [Co(2-CMSN)(4,4'-bipy)1.5(H2O)].0.65H2O, (I).
Complex (I) is isostructural to [Ni(2-CMSN)(4,4'-bipy)1.5(H2O)].0.75H2O (Jiang et al., 2012). The
of (I) contains one CoII ion, one 2-CMSN2- ligand, one and a half 4,4-bipy molecules (the other half being completed by inversion symmetry), one coordination water molecule and disordered lattice water molecules with an overall occupancy of 0.65. The coordination environment of the CoII ion is illustrated in Fig. 1. The CoII ion is six-coordinated in a slightly distorted octahedral CoN3O3 environment: two O atoms originate from one flexible carboxyl group and one rigid carboxyl group of two symmetry-related 2-CMSN2- ligands, three N atoms from three 4,4'-bipy molecules and one O atom from the water molecule. Two adjacent CoII ions are linked by two 2-CMSN2- ligands to give a dinuclear [Co2(2-CMSN)2] subunit with a Co···Co distance of 6.8600 (3) Å (Fig. 2). The dinuclear [Co2(2-CMSN)2] subunits are further bridged by 4,4'-bipy linkers to generate a final three-dimensional structure (Fig. 2). The disordered water molecules are situated in the free space of the resulting network. The 4,4'-bipy molecule that is situated on a centre of inversion is exactly planar, whereas the other has a dihedral angle between the two pyridyl rings [N2,C9—C13] and [N3, C14—C18] of 33.16 (7)°.In the crystal, intra- and inter-subunit O—H···O hydrogen bonds (Table 1) between the coordinating water molecule and carboxylate O atoms enhance the stability of the structure. Although the H atom position of the lattice water molecules could not be located, the O2W···O2 and O3W···S1 contacts of 2.864 (5) Å and 3.724 (9) Å, respectively, suggest also participation of these molecules in hydrogen bonding.

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. |

The construction of coordination polymers has aroused attention due to their potential applications, fascinating topologies and entanglement motifs (Wang et al., 2004).
2-Mercaptonanicotinic acid (2-H2MN) is a multifunctional ligand containing one carboxyl group, one thiol group and a pyridyl N donor atom. Some complexes based on the 2-MN2- ligand have been previously investigated, e.g. by Sun et al. (2011). Recently, on the basis of the 2-H2MN ligand, we have designed a new multi-carboxylate ligand, 2-carboxymethylsulfanyl nicotinic acid (2-H2CMSN) to construct novel complexes (Jiang et al., 2010; 2012). The 2-H2CMSN ligand is interesting because of its potential versatile coordination behavior, resulting from one rigid and one flexible carboxyl group. Due to the flexible carboxyl group, it is favorable for constructing novel network structures. Here we report the structure of the new title compound, [Co(2-CMSN)(4,4'-bipy)1.5(H2O)].0.65H2O, (I).
Complex (I) is isostructural to [Ni(2-CMSN)(4,4'-bipy)1.5(H2O)].0.75H2O (Jiang et al., 2012). The asymmetric unit of (I) contains one CoII ion, one 2-CMSN2- ligand, one and a half 4,4-bipy molecules (the other half being completed by inversion symmetry), one coordination water molecule and disordered lattice water molecules with an overall occupancy of 0.65. The coordination environment of the CoII ion is illustrated in Fig. 1. The CoII ion is six-coordinated in a slightly distorted octahedral CoN3O3 environment: two O atoms originate from one flexible carboxyl group and one rigid carboxyl group of two symmetry-related 2-CMSN2- ligands, three N atoms from three 4,4'-bipy molecules and one O atom from the water molecule. Two adjacent CoII ions are linked by two 2-CMSN2- ligands to give a dinuclear [Co2(2-CMSN)2] subunit with a Co···Co distance of 6.8600 (3) Å (Fig. 2). The dinuclear [Co2(2-CMSN)2] subunits are further bridged by 4,4'-bipy linkers to generate a final three-dimensional structure (Fig. 2). The disordered water molecules are situated in the free space of the resulting network. The 4,4'-bipy molecule that is situated on a centre of inversion is exactly planar, whereas the other has a dihedral angle between the two pyridyl rings [N2,C9—C13] and [N3, C14—C18] of 33.16 (7)°.
In the crystal, intra- and inter-subunit O—H···O hydrogen bonds (Table 1) between the coordinating water molecule and carboxylate O atoms enhance the stability of the structure. Although the H atom position of the lattice water molecules could not be located, the O2W···O2 and O3W···S1 contacts of 2.864 (5) Å and 3.724 (9) Å, respectively, suggest also participation of these molecules in hydrogen bonding.
