In the title complex, [Ir(C₁₇H₁₃N₂)₂(C₅H₇O₂)], the Ir^III atom is hexacoordinated in a distorted octahedral geometry by two C,N-bidentate 2-(5-methyl-3-phenylpyrazin-2-yl)phenyl (mdpp) ligands and one O,O-bidentate acetylacetonate ligand. The dihedral angles between the phenyl rings and the pyrazine ring are 9.56 (14) and 58.99 (14)° for one mdpp ligand and 9.34 (14) and 79.94 (15)° for the other.

Comment top

In recent decades, organic light-emitting diodes (OLEDs) based on phosphorescent complexes have attracted increasing attention due to their potential applications in full-color flat panel displays (Baldo et al., 1998, 2000). Among these phosphorescent complexes, iridium cyclometalates often exhibit favorable photoproperties for OLEDs including short phosphorescent lifetimes, high quantum efficiencies and good stability (Liu et al., 2008; Hwang et al., 2005; Tsuboyama et al., 2003). Zhang et al. (2005) demonstrated a high efficiency yellow OLED using [Ir(mdpp)₂(acac)] [mdpp = 2-(5-methyl-3-phenylpyrazine-2-yl)phenyl, Hacac = acetylacetone] as the dopant. In this work, we synthesized the title complex, [Ir(mdpp)₂(acac)], and investigated its crystal structure.

The molecular structure of the title complex is shown in Fig. 1. The Ir^III ion has an approximately octahedral coordination geometry and is hexacoordinated by two C atoms and two N atoms from two C,N-bidentate mdpp ligands, which exhibit cis-C,C and trans-N,N chelate dispositions, and two O atoms from one O,O-bidentate acac ligand. The bond lengths of Ir—N,O,C are listed in Table 1. Due to steric interactions, the phenyl groups are not coplanar with the pyrazine group. The dihedral angles between the phenyl rings and pyrazine ring are 58.99 (14)° (between the N1,N2,C6–C9 ring and C11–C16 ring), 9.56 (14)° (between the N1,N2,C6–C9 ring and C17–C22 ring), 79.94 (15)° (between the N3,N4,C23–C26 ring and C28–C33 ring) and 9.34 (14)° (between the N3,N4,C23–C26 ring and C34–C39 ring).

Experimental top

The title complex was obtained according to the procedure previously reported (Zhang et al., 2003, 2005). Orange red crystals of the title complex suitable for X-ray structure analysis were grown from a mixture of 3 ml dichloromethane and 12 ml ethanol.

Special details top

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.
