Tris(bipyridine)cobalt(II) hexafluorophosphate was prepared by stirring a mixture of a solution containing Co(O2CC2F5)2 (0.100 g, 0.25 mmol) and bipyridine (0.120 g, 0.77 mmol) in ethanol (10 ml). The reaction mixture was stirred for 2 h. After this time NaPF6 (0.100 g, 0.59 mmol) was added and stirred for 1 h. Solid of title compound was obtained by slow evaporation of an ethanol solution in refrigerator (Yield 0.150 g, 79%; m.p. 594 K). Yellow block crystals were obtained in acetonitrile/ethanol (1:1) solution after few days. ATR-IR: 1603 ν(C=N), 1566 ν(C=C) cm-1.
Hydrogen atoms were included in calculated positions (C—H = 0.95 Å) riding on the bonded atom with isotropic displacement parameters set to 1.2Ueq(C) for all hydrogen atoms. All non-H atoms were refined with anisotropic displacement ellipsoids. Merohedral twinning is indicated and applying the twin instruction [TWIN 0 1 0, 1 0 0, 0 0 - 1] with a BASF parameter in SHELXTL (Sheldrick, 2008), the R1 value drops to 0.049 (0.0886 without TWIN Instruction) and wR2 value drops to 0.0883 (0.2284 without TWIN instruction).
The reaction of Cobalt(II) pentafluoropropionate with NaPF6 in the presence of 2,2'-bipyridine yields the coordination compound tris(bipyridine)cobalt(II) hexafluorophosphate (1), [Co(bipy)3][PF6]2. Crystals were grown by allowing slow evaporation of the complex in ethanol. The title complex crystallizes in the space group P3(2) in contrast to the related compound [Co(bipy)3][Mo6O19]2 which crystallizes in P21/n (Liu et al., 2010). The structure of (1) is shown in Fig. 1. Within the divalent complex cations, the cobalt atoms are each surrounded by six N atoms of three chelating bipy ligands to complete a distorted octahedral coordination with d(Co—N) = 2.098 (7) – 2.149 (8) Å, the cis and trans N—Co—N bond angles in the range 76.6 (3) – 96.9 (3) and 167.6 (3) – 170.5 (3)°, respectively. Such distances are similar to those found in other related structures (Liu et al., 2008, Chygorin et al. 2012). There has been great interest in homoleptic imine complexes, because of great potential applications in many fields such as, catalysis, material science and medicine. The crystal packing of the title compound is presented in Fig. 2. The crystal structure is stabilized by weak intermolecular C—H···F bonds.

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. |

The reaction of Cobalt(II) pentafluoropropionate with NaPF6 in the presence of 2,2'-bipyridine yields the coordination compound tris(bipyridine)cobalt(II) hexafluorophosphate (1), [Co(bipy)3][PF6]2. Crystals were grown by allowing slow evaporation of the complex in ethanol. The title complex crystallizes in the space group P3(2) in contrast to the related compound [Co(bipy)3][Mo6O19]2 which crystallizes in P21/n (Liu et al., 2010). The structure of (1) is shown in Fig. 1. Within the divalent complex cations, the cobalt atoms are each surrounded by six N atoms of three chelating bipy ligands to complete a distorted octahedral coordination with d(Co—N) = 2.098 (7) – 2.149 (8) Å, the cis and trans N—Co—N bond angles in the range 76.6 (3) – 96.9 (3) and 167.6 (3) – 170.5 (3)°, respectively. Such distances are similar to those found in other related structures (Liu et al., 2008, Chygorin et al. 2012). There has been great interest in homoleptic imine complexes, because of great potential applications in many fields such as, catalysis, material science and medicine. The crystal packing of the title compound is presented in Fig. 2. The crystal structure is stabilized by weak intermolecular C—H···F bonds.
