The green colored Trans-Hydrogen dichlorobis(dimethylgloximato) cobaltate(III), H[Co(dmgH)2Cl2] was prepared by the method reported in the literature (Phor, et al., 1985). Using this complex, as the starting material, the cobaloxime: pyrazine-2-tert-butylcarboxamidopyrazinechlorocobaloxime viz., [Co(dmgH)2(t-BuPzAM)Cl] was prepared by adopting the method reported earlier (Vijayaraghavanan & Dayalan, 1992). Hydrogen dichlorobis (dimethylglyoximato)cobaltate(III) (0.01 mole) and 0.01 mole of Pyrazine-2-tert-butylcarboxamide were taken in about 60 ml of absolute alcohol and stirred for 1 hr, with warming over hot water bath, until the green colour due to dichlorocobaloxime was discharged to get the required brown colored complex. The resulting complex was filtered, washed with alcohol and dried in a vacuum desiccator. Crystals of the complex were grown in ethanol by slow evaporation.
Even though the unit cell satisfies orthorhombic metric conditions within the limits of s.u., Rint pointed clearly to a monoclinic symmetry (Rint ortho=0.59, Rintmono=0.027). The structure was solved and refined in P21/c. All the H atoms were located in a difference Fourier map. H atoms linked to carbon and oxygen atoms were relocated at idealized positions and allowed to ride with C—H(aromatic): 0.93A%, and 1.2UeqC; C—H(tertiary): 0.96A%, and 1.5UeqC; O—H: 0.82A%, and 1.5UeqO. N—H hydrogen distances were restrained (N—H:0.83 (1)) and refined isotropically. Ther disordered crystal water molecule is split into two equally populated sites (O11 and O11', with 50% occupancy each).
Dimethylglyoximatocobalt(III) complexes, generally known as cobaloximes, have been studied extensively as model compounds for vitamin-B12 (Trommel, et al., 2001; Ohkubo & Fukuzumi, 2005). Most of the work on cobaloximes include electron-transfer reactions (Dayalan & Vijayaraghavan,2001) and catalytic activity (Razavelt, et al., 2005) in solution. There are few literature evidences (Gupta, et al., 2000; Gupta, et al., 2001; Gupta, et al., 2004) relating the structural aspects of cobaloximes. We report here the synthesis, physical characterization and the crystal structure of a typical cobaloxime viz., pyrazine-2-tert-butylcarboxamidochlorocobaloxime. Figure 1 shows the ORTEP representation of the two independent molecules in the asymmetric unit, with 50% anisotropic ellipsoids. Figure 2 presents a packing diagram of the structure depicting the hydrogen bonding interactions. The geometry around the metal atom is octahedral; the bonds to chlorines and pyrazine N atoms are almost perpendicular to the mean glyoximate planes. The difference Fourier clearly shows one O—H group in each one of the glyoximate moieties attached to Co2, while in those attached to Co1, both hydrogen atoms are bound to only one of the glyoximate moieties. The planar glyoximate groups subtend dihedral angles of 7.76 (13)° (Co1) and 0.95 (13)° (Co2). There are strong intra molecular O—H···O hydrogen bonds linking the glyoximate moieties (Figure 2). There is one crystal water molecule per asymmetric unit (disordered into two positions O11, O11') hydrogen bonded to the chlorine atoms Cl2, attached to Co2. The corresponding water H atoms could not be located in the difference map and were not included in the model.

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. |

Dimethylglyoximatocobalt(III) complexes, generally known as cobaloximes, have been studied extensively as model compounds for vitamin-B12 (Trommel, et al., 2001; Ohkubo & Fukuzumi, 2005). Most of the work on cobaloximes include electron-transfer reactions (Dayalan & Vijayaraghavan,2001) and catalytic activity (Razavelt, et al., 2005) in solution. There are few literature evidences (Gupta, et al., 2000; Gupta, et al., 2001; Gupta, et al., 2004) relating the structural aspects of cobaloximes. We report here the synthesis, physical characterization and the crystal structure of a typical cobaloxime viz., pyrazine-2-tert-butylcarboxamidochlorocobaloxime. Figure 1 shows the ORTEP representation of the two independent molecules in the asymmetric unit, with 50% anisotropic ellipsoids. Figure 2 presents a packing diagram of the structure depicting the hydrogen bonding interactions. The geometry around the metal atom is octahedral; the bonds to chlorines and pyrazine N atoms are almost perpendicular to the mean glyoximate planes. The difference Fourier clearly shows one O—H group in each one of the glyoximate moieties attached to Co2, while in those attached to Co1, both hydrogen atoms are bound to only one of the glyoximate moieties. The planar glyoximate groups subtend dihedral angles of 7.76 (13)° (Co1) and 0.95 (13)° (Co2). There are strong intra molecular O—H···O hydrogen bonds linking the glyoximate moieties (Figure 2). There is one crystal water molecule per asymmetric unit (disordered into two positions O11, O11') hydrogen bonded to the chlorine atoms Cl2, attached to Co2. The corresponding water H atoms could not be located in the difference map and were not included in the model.
