(Received 4 August 2013; accepted 22 September 2013; online 9 October 2013)

The title compound, [Ir(C10H5F2N2)2(C5H7O2)], has a distorted octa­hedral coordination geometry around the IrIII atom, retaining the cis-C,C/trans-N,N chelate disposition in two 2,6-di­fluoro-3-(pyridin-2-yl-κN)pyridin-4-yl ligands which are nearly mutually perpendicular [dihedral angle = 82.75 (15)°]. The mol­ecular structure is stabilized by weak C—H⋯O and C—H⋯F hydrogen-bond inter­actions. The crystal structure is stabilized by ππ stacking inter­actions (centroid–centroid distance = 3.951 Å).

Comment top

The phosphorescent cyclometalated Iridium(III) complexes have received considerable attention in the fabrication of phosphorescent organic light emitting diodes for their high quantum efficiencies, relatively short phosphorescent lifetimes. Lee et al. (2009) reported a fac-Ir(III) complex, fac-Ir(dfpypy)3, using 2',6'-Difluoro-2,3'-bipyridine (dfpypy)ligand, this complex exhibits intense blue emission with high color purity. Recently, a heteroleptic Ir complex,(dfpypy)2Ir(acac), incorporating dfpypy and acetyl acetone, was synthesized by our group and the blue phosphorescent electroluminescence devices were fabricated by doped (dfpypy)2Ir(acac) into PVK host. We report herein on its crystal structure.

The structure of the title complex is shown in Fig. 1. The coordination at the iridium atom is octahedral. The title compound displays shorter Ir–C [1.968 (5) and 1.975 (6) Å] and Ir–N [2.036 (4) and 2.047 (4) Å] bond distances, compared with those in fac-Ir(dfpypy)3 [1.997 (5)\sim 2.005 (5) Å for Ir–C bands and 2.116 (4)~2.135 (4) Å for Ir–N bands]. Ir–O bands are 2.143 (3) and 2.147 (3), respectively.

The interplanar angles between the chelate rings, for IrO2C3 ring A (Ir1, O2, C23, C22, C21, O1) to the IrNC3 ring B (Ir1, N1, C5, C6, C7) and C (Ir1, N3, C15, C16, C17) are 89.37 and 87.22 °, respectively, while the IrNC3 rings, B and C, are inclined at an angle of 86.71 °. The dihedral angles between two pyridyl rings of fluorine-substitution bipyridine ligands are 6.94 ° for bipyridine involving N1, N2 atoms and 8.24 ° for that involving N3, N4 atoms, which has bigger dihedral angles than those in fac-Ir(dfpypy)3 [3.84~ 5.63]. The molecular structure is stabilized by weak C–H···O and C–H···F hydrogen bonds interactions, Table 1. The crystal structure is stabilized by π-π stacking interactions(Cg1- Cg2 distance 3.951Å, Cg1=N1-C1/C5 ; Cg2= N3-C11/C15)

Experimental top

2',6'-Difluoro-2,3'-bipyridine (dfpypy) ligand was prepared according to the method of Lee et al. (2009). The Ir(III) µ-dichloro-bridged dimer, [IrCl(dfpypy)2]2 was prepared according to the method of Lamansky et al. (2001a). A mixture of [IrCl(dfpypy)2]2 (0.82 mmol, 1.04 g), acetyl acetone (4.2 mmol, 0.42 g), anhydrous Cs2CO3 (0.8 mmol. 0.265 g) and 2-ethoxyethanol (30 ml) was stirred under inert atmosphere at 95 °C for 15 h. After cooling to room temperature, the precipitate was fitered off, washed with water and hexane and methanol. The crude product was purified by chromatography on silica gel [eluent: petroleum ether and ethyl acetate, v/v = 3:1]. The greenish yellow crystals, suitable for X-ray analysis, were obtained by slow diffusion of methanol into the dichloromethane solution of the title complex.

Refinement top

H atoms were placed at calculated positions and refined as riding atoms: C–H = 0.93, 0.96 Å for CH (aromatic) and CH3 H-atoms, respectively, with Uiso(H) = k × Ueq(C), where k = 1.5 for CH3 H atoms, and k = 1.2 for all other H atoms.

Experimental. Absorption correction: CrysAlisPro, Agilent Technologies, Version 1.171.35.11 (release 16-05-2011 CrysAlis171 .NET) (compiled May 16 2011,17:55:39) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

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.
