The title compound, [Ir(C12H8NO)Cl2(C12H9NO)]·CH2Cl2, which was obtained from the reaction of iridium(III) chloride trihydrate and 2-benzoylpyridine, contains an IrIII atom coordinated by two N, one O, one C and two Cl atoms in trans positions, forming a distorted octahedral environment. The solvent molecule CH2Cl2 is disordered over two positions with an occupancy of 0.8:0.2.

All procedures involving Ir(III) species were carried out under nitrogen gas atomosphere. 2-Benzoylpyridine (10.0 mmol) and 0.4 equiv. of IrCl3.H2O (Next Chimica) were heated in a 3:1 mixture of 2-ethoxyethanol and water. This slurry was heated to 100 °C for 24 hours. After cooling to room temperature, the precipitate was filtered off and washed with deionized water, followed by 2 portions of n-hexane and ether. The orange–reddish single crystals were obtained from the solutions of dichlomathane and n-hexane mixture (1:1) in 43% yield.
All H atoms bonded to C atoms were placed in calculated positions, with C—H = 0.96 Å, and treated as riding atoms, with Uiso(H) = 1.2Ueq(C). The solvent molecule CH2Cl2 was refined as disordered with an 80/20 occupancy for the two molecules.

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

Several studies have been reported in cyclometallation of orthometallated ligands such as anionic ppy (ppyH is 2–phenylpyridine). For instance, Rh(Hbzpy)(bzpy)Cl2 (bzpy is 2–pyridyl–2–phenonide) was obtained from the reaction of rhodium (III) chloride trihydrate with 2–benzoylpyridine (Hbzpy) in 2–methoxyethanol for 4 d at room temperature (de Geest & Steel, 1995). The orthometallated complex which they reported had a five–membered N,O metallacycle containing the chelated Hbzpy ligand and a six–membered N,C metallacycle containing the chelated bzpy ligand, on the basis of NMR chemical–shift analysis. Moveover, the structural study of the orthometallated RhIII complex was reported in order to make sure the stereochemistry (Tseng et al., 2005). However, the synthesis and structural study of the according iridium complex was never reported. We report herein the synthesis and characterization studies of the title orthometallated IrIII complex, (I), containing 2–pyridyl phenone.
In the orthometallated title compound, the Ir atom is hexacoordinated by two equivalents of 2–benzoylpyridine, forming a pseudo–octahedral geometry, with two Cl ligands in a trans orientation. The pyridyl N atom of the Hbzpy ligand is trans to the N atom of the bzpy ligand, where one of the ligands is κ2–(N,C)–cyclometallated and the other is κ2–(N,O)–coordinated. Cyclometallation leads to a boat conformation, with atoms Ir and C18 above the N2—C17—C19—C24 plane (Fig. 1). The pyridyl ring of the Hbzpy ligand and the phenyl ring of the bzpy ligand are mutually stacked [C1—N1—C24—C23 = 48.8 (2)°] (Table 1). The five-membered chelate ring deviates slightly from planarity [N1—C5—C6—O1 = -10.9 (3)°] and is inclined to the phenyl plane [C5—C6—C7—C12 = -39.1 (4)°]. There are no short intermolecular contacts.
