To a solution of 2-(bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl)pyridine (0.2 mmol, 56.3 mg) in 10 ml of methanol, Co(NO3).6H2O (0.1 mmol, 29.1 mg) was added. The solution was stirred at r.t. for 30 min. Yellow and block-like crystals were obtained by evaporation after one week [Yield: 46 wt%].
All the H atoms were included in calculated position and refined in the riding-model approximation: C—H = 0.93, 0.96 and 0.98 Å CH(aromatic), CH3 and CH(methine), respectively, with Uiso(H)= k ×Ueq(C), where k = 1.5 for CH3 H atoms and = 1.2 for other H atoms.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
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. |

Rigid ligands have captivated attention not only because of their various coordination possibilities and high structural stability, but also because of their potential applications in electrochemistry (Morin et al., 2011), catalysis (Zhang et al., 2009), and fluxional behaviour (Otten et al., 2009; Arroyo et al., 2000). In addition, N-heterocyclic rigid scorpion-type ligands have attracted increased attention due to their nitrogen coordination sites (Reger et al., 2005; Liu et al., 2011). Herein, we report on the synthesis and crystal structure the title complex, [CO(bpz*mpy)2](NO3)2, synthesized by the reaction of 2-(bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl)pyridine (bpz*mpy), with Co(NO3).6H2O.
The molecular structure of the title complex is shown in Fig. 1. The Co atom is situated on a twofold rotation axis and is coordinated by 6 N- atoms from two (bpz*mpy) ligands. The Co—N bond lengths range from 2.131 (2) to 2.149 (3) Å, hence the central cobalt ion has a slightly distorted octahedral coordination sphere.
In the crystal, molecules are linked by weak C—H···O interactions (Table 1 and Fig. 2).
