Abstract

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.

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.
