In the centrosymmetric title dimeric CoII complex, [Co2(C7H3NO4)2(C6H6N4OS2)2(H2O)2].10H2O, each CoII cation has a distorted octa­hedral coordination geometry formed by a diamino­bithia­zole (DABT) ligand, two pyridine-2,3-dicarboxyl­ate anions and a coordinated water mol­ecule. With its two carboxyl­ate groups, the pyridine-2,3-dicarboxyl­ate anion bridges two CoII ions to form the dimeric complex. Within the chelating DABT ligand, the two thia­zole rings are twisted with respect to each other [dihedral angle = 3.29 (19)°]. Extensive N—H...O, O—H...O and O—H...N hydrogen bonding helps to stabilize the crystal structure.

Comment top

Transition metal complexes of 2,2'-diamino-4,4'-bi-1,3-thiazole (DABT) have shown biological activities such as the effective inhibitors of DNA synthesis of the tumor cells (Waring, 1981; Fisher et al., 1985). As part of serial structural investigation of metal complexes with DABT (Liu & Xu, 2004), the title CoII complex was recently prepared and its X-ray structure is presented here.

The molecular structure of the title compound is shown in Fig. 1. The complex of CoII has a distorted octahedral coordination geometry (Table 1) formed by one of DABT ligand, one of pyridine-2,3-dicarboxylate anion, one of coordinated water and one of adjacent pyridine-2,3-dicarboxylate anion.

Within the complex, the DABT molecule shows approximately coplanar configuration with the dihedral angle of 3.29 (19)° between thiazole rings defined by C1, C2, C3, S1, N1 and C4, C5, C6, S2, N3. This is compare to 4.57 (7)° found in [Mn(DABT)(oxydiacetate)] (Luo et al., 2004) and 6.52 (9)° found in [Cu(DABT)(oxydiacetato)] (Wu et al., 2003), but different from the 17.23 (7)° found in [Cr(C4H5NO4)(C6H6N4S2)(H2O)]Cl (Liu et al., 2004) and 20.02 (8)° in [Ni(DABT)(iminodiacetate)] (Liu & Xu, 2005). Bond lengths C6—N4 [1.334 (4) Å] and C3—N2 [1.326 (4) Å] imply the existence of electron delocalization between thiazole rings and amino groups.

Within the pyridine-2,3-dicarboxylate anion, one oxygen atom (O11) of one carboxyl group of the pyridine-2,3-dicarboxylate anion and the nitrogen atom (N11) of pyridine ring chelate to CoII atom and one oxygen atom (O13) of another carboxyl group of the pyridine-2,3-dicarboxylate anion chelates to another neighboring CoII atom to form the dimeric complex across an inversion centre. The dihedral angles between the pyridine ring and two carboxyl group plans are 5.84 (7) and 84.82 (11)° for the plan formed by C11, C16, O11, O12 and the plan formed by C12, C17, O13, O14 respectively. Otherwise, another uncoordinated oxygen atom (O12 and O14) hydrogen bonded to the lattice water within the complex (Fig. 1 and Table 2), which helps to stabilize the crystal structure.

Experimental top

An aqua solution (20 ml) containing DABT (0.20 g, 1 mmol) and CoCl2.6H2O (0.23 g, 1 mmol) was mixed with an aqueous solution (10 ml) of pyridine-2,3-dicarboxylic acid (0.17 g, 1 mmol) and NaOH (0.08 g, 2 mmol). The mixture was refluxed for 6 h. After cooling to room temperature the solution was filtered. Single crystals of the title compound were obtained from the filtrate after 3 d.

Refinement top

H atoms on carbon atoms were placed in calculated positions with C—H distances = 0.93 Å (aromatic), and were included in the final cycles of refinement in riding mode with Uiso(H) = 1.2Ueq(C). H atoms of amino groups and coordinated water molecule were located in a difference Fourier map and included in the structure factor calculations in riding mode with Uiso(H) = 1.2Ueq(N,O). H atoms of lattice water molecules were located in a difference Fourier map and refined as riding in their as-found relative positions, 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.
