The title compound, [Ru(C10H8N2)2(CH3CN)2](PF6)2, a six-coordinate ruthenium(II) complex, crystallizes in the monoclinic C2/c space group showing different symmetry from the previously reported P21/n. A crystallographic twofold rotation axis passes through the Ru atom. The two C atoms and H atoms of one acetonitrile ligand are disordered over two positions, with site occupancy factors of ca 0.55 and 0.45. Three F atoms are disordered over two positions, with similar site occupancy factors.

Comment top

The structures of cis-bis(acetonitrile)bis(2,2'-bipyridine) ruthenium(II) diperchlorate (Chattopadhyay et al., 2004), trans-bis(acetonitrile)bis(2,2'-bipyridine) ruthenium(II) diperchlorate (Cordes et al., 1992), and the title complex (Heeg et al., 1985) have been reported previously. We present herein the crystal structure of the title compound (I) again with the same unit cell as Heeg et al.'s within the experimental error, but it crystallizes in the monoclinic C2/c space group other than the earlier P21/n.

The atom-numbering scheme of compound (I) is shown in Fig.1, while selected bond distances and angles are given in Table 1. The Ru—N bond lengths and bond angles are comparable with those in literature. The presence of acetonitrile molecules in this Ru(II) complex can be verified by routine characterization. The main difference between our data and Heeg et al.'s is the assignment of the space group. Our results demonstrate the higher symmetry of molecule (C2/c instead of P21/n), and two carbon atoms of monodentate acetonitrile molecules are refined disorderly. We failed to solve this structure by assigning the reported P21/n space group.

Experimental top

The title complex (I) was obtained by refluxing equal molar ratio of Ru(bpy)2Cl2.H2O (0.02 g, 0.04 mmol) and a pre-synthesized schiff base, 4-[2-(pyridin-4-ylimino)-ethyl]-benzoic acid (0.01 g, 0.04 mmol) in 30 ml acetonitrile for 1 h. The mixture was cooled to room temperature and a 10 ml saturated NH4PF6 solution was added. Orange single-crystal of (I) suitable for the X-ray diffraction analysis was grown directly from the mother liquor as a by-product. Elemental analysis, calculated for RuC24H22N6P2F12: C, 36.70; H, 2.82; N, 10.70%; found: C, 36.55; H, 2.99; N, 10.48%. IR (KBr): 3123, 3094, 3003, 2938, 1606, 1468, 1449, 1314, 1276, 1243, 1164, 1040, 833, 762, and 557 cm-1. 1H NMR (d6-DMSO): δ (p.p.m.) 9.364 (2H), 8.778 (2H), 8.649 (2H), 8.353 (2H), 8.031 (2H), 7.931 (2H), 7.575 (2H), 7.373 (2H), 2.437 (6H).

Refinement top

The non-hydrogen atoms were refined anisotropically, whereas the H atoms were placed in geometrically idealized positions (C—H = 0.93–0.96 Å) and refined as riding atoms, with Uiso(H) = 1.5Ueq(for methyl C) or Uiso(H) = 1.2Ueq(C) for the other C atoms. F2, F3 and F6 atoms of hexafluorophosphate are refined over two sites with 0.557 (17):0.443 (17) site occupancy factors. Due to the disorder of acetonitrile molecules, the 'similar Uij' restraints (SIMU) were used to restrain the Uij components of neighboring atoms (N3—C11 and N3—C11', six for each). The effective standard deviations is set as 0.004 for N3—C11 and 0.003 for N3—C11', respectively.

Special details top

Experimental. The structure was solved by direct methods (Bruker, 2000) and successive difference Fourier syntheses.

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.
