In the crystal structure of the title salt, (C₇H₇N₂S)₂[Co(C₈H₈O₅)₂]·6H₂O, the heterocyclic N atom of the 2-aminobenzothiazole molecule is protonated. The Co^II atom is situated on an inversion centre and exhibits a slightly distorted octahedral CoO₆ coordination defined by the bridging O atoms of the bicycloheptane unit and four carboxylate O atoms of two symmetry-related and fully deprotonated ligands. The crystal packing is stabilized by N—H⋯O hydrogen bonds between the cations and anions and by O—H⋯O hydrogen bonds including the crystal water molecules.

Comment top

7-oxabicyclo[2,2,1] heptane-2,3-dicarboxylic anhydride (norcantharidin) derived from cantharidin is a lower toxicity anticancer drug (Shimi et al., 1982). Cobalt was recognized as an essential metal element widely distributed in biological systems such as cells and body (Jiao et al., 2005). Several related cobalt complexes with the same ligand (Wang et al., 1988) and with the ligand and with imidazole (Wang et al., 2009) have been reported.

In the title complex, (C₇H₇N₂S)⁺₂[Co(C₈H₈O₅)₂]^2-(H₂O)₆, the Co^II ion is located on a crystallographic centre of inversion. Two bridging oxygen atoms of the bicycloheptane units and four carboxylate oxygen atoms give rise to a slightly distorted octahedral coordination environment around the Co^II atom. The bond angles O2—Co1—O2ⁱ, O4—Co1—O4ⁱ and O5—Co1—O5ⁱ (i: -x+1, -y, -z.) are 180°, while the bond angles O4—Co1—O2 and O2—Co1—O4ⁱ open up slightly from 87.71 (9)° to 92.29 (9)°, resulting in a slight distortion from the ideal octahedral geometry. The crystal packing is stabilized by N—H···O hydrogen bonds between the cations and anions and by O—H···O hydrogen bonds including the crystal water molecules.

The crystal structure of (C₇H₇N₂S)⁺₂[Co(C₈H₈O₅)₂]^2-(H₂O)₆ is isotypic with that of the Mn analogue (Wang et al., 2010) where slightly longer metal—oxygen bonds are observed.

Experimental top

Norcantharidin, cobalt acetate and 2-aminobenzothiazole were dissolved in 15 mL distilled water. The mixture was sealed in a 25 mL Teflon-lined stainless vessel and heated at 443 K for 3 d, then cooled slowly to room temperature. Pink crystals suitable for X-ray diffraction were obtained.

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.
