The mixture of CoCl2 (0.1 mmol) and L (0.2 mmol) in 10 ml of ethanol was stirred for 20 min at room temperature. After filtration, the mother solution was allowed to stand for one week to give blue crystals suitable for X-ray diffraction analysis.
All H atoms bounded to C atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93Å (CH) and Uiso(H) = 1.2Ueq(C), C—H = 0.97Å (CH3) and Uiso(H) = 1.5Ueq(C).

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. |

Over the past few years, a number of coordination compounds derived from the prototypical ligands of 4-(pyridin-n-yl)pyrimidine-2-thiol (n = 2, 3, 4) and their S-modified derivatives have been reported by our group (Huang et al., 2007; Dong et al., 2009; Zhu et al., 2009). In light of our previous study, it is apparent that the coordination chemistry of such type of ligands is profoundly effected by the nature of the S atom. As part of our research program, we present here a discrete CoII coordination compound with ligand L (L = 2-(methylthio)-4-(pyridin-2-yl)pyrimidine) bearing a methylthio group.
The asymmetric unit of the title compound owns half of one molecule. A twofold rotational axis passes through the CoII atom. As depicted in Fig. 1, the CoII atom in the title compound is surrounded by two L ligands and two Cl atoms, adopting an octahedral coordination geometry. Like 2,2'-bipyridine, the ligand L serves as a chelating ligand through two N atoms with Co—N bond distances being 2.148 (3)Å and 2.299 (3) Å, whilst two Cl atoms are bound to the CoII atom in cis positions with equal Co—Cl bond distance (2.434 Å). In L, the pyridyl and pyrimidinyl rings are twisted by a dihedral angle of 9.9 (1)°, and the methylthio group is not involved into the metal coordination as a result of the weak affinity of the S atom for Co.
