Abstract top

In the title compound, [Ir(C11H8N)2(C12H10NO)(H2O)]·0.5C2H6O2, the iridium center is coordinated by two N atoms and two C atoms from two 2-(2-pyridyl)phenyl (ppy) ligands, one N atom from the N-(1-naphthyl)acetamide ligand and one water O atom, forming a distorted octahedral environment. Molecules are linked by intermolecular O-H...O hydrogen bonds formed by the coordinated water molecule and the amide O atom of the N-(1-naphthyl)acetamide ligands.

Comment top

Since the initial work by Thompson and Forrest (Baldo et al., 1998), there have been considerable attention focused on designing homoleptic Ir triscyclometalates (CÑ)3Ir and heteroleptic Ir complexes (CÑ)2Ir(LX) for their application in organic light emitting diodes (OLEDs), where CÑ is a general abbreviation used hereafter for a cyclometalating ligand and LX is an ancillary ligand. (CÑ)2Ir(LX) complexes, containing cyclometalating ligands 2-pyridylphenyl, have already been incorporated with different kinds of ancillary ligands, such as β-diketonate, 2-picolinic acid, to exploit their potential application in OLEDs. (Adachi et al., 2000; Lamansky et al., 2001; Beeby et al., 2003; You & Park, 2005). However, among all the ancillary lignads used in (CÑ)2Ir(LX) complexes, N-(1-naphthyl)acetamide has never been studied..

In this paper, we report the crystal structure of (CÑ)2Ir(LX) with N-(1-naphthyl)acetamide as ancillary ligand, it is a solvated neutral mononuclear [Ir(ppy)2(N-acetyl-1-naphthylamino)(H2O)] (ppy=2-pyridylphenyl) complex. The Ir atom has a distorted octahedral geometry involving two ppy ligands, one N-(1-naphthyl)acetamide ligand and one water molecule.The average bond lengthes from two N atoms and two C atoms in two ppy ligands to iridium center are Ir—Nav = 2.048Å and Ir—Cav = 1.987Å respectively, the bond lengthes from N atom in the N-acetylnaphthylamine ligand and the O atom in aqua to Ir atom are Ir—N=2.217 (5)Å and Ir—O= 2.219 (4).(Table 1).

The molecules of the title complexes are linked by O—H···O intermolecule hydrogen bonds formed by the coordinated water molecules and amido O atom of the N-acetyl-1-naphthylamino ligands.(Fig. 2.)

Experimental top

0.107 g [(ppy)2IrCl]2 (1 eq.) and 0.047 g (2.5 eq.) N-(1-naphthyl)acetamide were dissolved in dichlomethane, 0.054 g sodium methanol(10eq.) then added to the mixture to neutralize the hydrochloric acid that produced in the reaction. The reaction was stirred at room temperature for 24 h. After the reaction, the solvent was removed and the residua was washed with hot water and ether. The crude product was separated by chromatography on silica gel with dichloromethane as eluent to give a yellow solid. Single crystals suitable for X-ray diffraction were grown by slow diffusion of ethylene glycol solution.

Refinement top

All H atoms were placed in calculated positions with C—H = 0.93 (aromatic), 0.97 Å (methylene), and refined using a riding model with Uiso(H) = 1.2Ueq(C,N). Water H atoms were tentatively located in difference Fourier maps and were refined with distance restraints of O–H = 0.82 Å and H···H = 1.29 Å, each within a standard deviation of 0.01 Å; and with Uiso(H) = 1.5 Ueq(O).

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.
