(Received 21 October 2011; accepted 2 November 2011; online 5 November 2011)

In the title compound, [Co(C5H7O2)2(C12H8N2)], the CoII cation lies on a twofold rotation axis and is coordinated by four O atoms from two acetyl­acetonate (acac) ligands and two N atoms from a 1,10-phenanthroline (phen) ligand in a slightly distorted octa­hedral environment, with Co—O bond lengths of 2.0565 (11) and 2.0641 (11) Å and Co—N bond lengths of 2.1630 (12) Å. In the crystal, there are no significant hydrogen-bonding or π–π inter­actions.

Comment top

Metal β-diketonate compounds attracted great interest, because metal complexes of β-diketonate derivatives are useful building blocks for design of porous and supramolecular materials and can be good precursors in metal-organic chemical vapour deposition (MOCVD) (Garibay et al., 2009; Kaitner et al. 2008).

In the title molecule (Fig. 1), the cobalt(II) cation lies on a twofold axis, and is surrounded by six donor atoms arranged at the vertices of a distorted octahedron. The coordination polyhedron of CoII is formed by four oxygen atoms of two symmetry related 2,4-pentanedionato ligands and two nitrogen atoms of 1,10-phenantroline. Consequently, the octahedron is defined by two symmetry-independent cobalt-oxygen bonds Co–O1 2.0565 (11) Å (in trans position to N1 of the phen ligand) and Co–O2 2.0641 (11) Å (in cis position to N1 of the phen ligand) and a cobalt-nitrogen bond Co–N1 2.1630 (12) Å. These bond lengths are similar with the ones observed in adducts (1,10-phenanthroline)bis(1,3-diphenyl-1,3-propanedionato)cobalt(II) (Meštrović & Kaitner 2006) and (2,2'-bipyridine)bis(4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedionato)cobalt(II) (Riblet et al., 2010). The discrepancy of the coordination polyhedron of CoII from the ideal octahedral arrangement is well illustrated by the angles O1–Co–O2 and N1–Co–N1 of 87.62 (4)° and 77.20 (6)°, respectively. In the crystal structure, there are no hydrogen-bonding or π–π interactions.

Experimental top

(1,10-Phenanthroline-κ2N,N')bis(2,4-pentanedionato-κ2 O,O')cobalt(II) was prepared according to the published procedure (Ellern & Ragsdale, 1968). 0.25 mmol (0.064 mg) of bis(2,4-pentanedionato-κ2 O,O')cobalt(II) was disolved in 5 ml of warm chloroform and than 0.25 mmol (0.045 mg) of 1,10-phenantroline was added. Orange crystals suitable for single-crystal X–ray diffraction were obtained after slow evaporation.

Refinement top

Although H atoms were visible in a difference Fourier map they were treated in riding mode in geometrically idealized positions, with C—H = 0.93 (aromatic and alkenyl) or 0.96 Å (CH3), and with Uiso(H) = kUeq(C), where k = 1.5 for methyl groups, which were permitted to rotate but not to tilt, and 1.2 for all other H atoms. To improve the refinement results, one reflection with too high value of δ(F2)/e.s.d. and with Fo2 < Fc2 was excluded from the refinement.

Special details top

Experimental. 346 frames in 4 sets of φ scans + ω scans. Rotation/frame = 2.0 °. Crystal-detector distance = 34.7 mm. Measuring time = 20 s/°.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
