(2-Benzoyl-1-phenylethenolato-κ²O,O′)bis[2-(1-phenyl-1H-benzimidazol-2-yl)phenyl-κC¹]iridium(III) dichloromethane disolvate

Abstract

We present here synthesis and crystal structure of a neutral IrIIIcomplex, [Ir(C19H13N2)2(C15H11O2)]·2CH2Cl2or [Ir(C^N)2O^O]·2CH2Cl2, where C^N is 1,2-diphenyl-1H-benzimidazole and O^O is 2-benzoyl-1-phenylethenolate. The coordination sphere of the IrIIIatom, located on a twofold rotation axis, is that of a slighlty distorted C2N2O2octahedron, with the N atoms in atransconfiguration. In the crystal, complex molecules assemble through weak C—H...π interactions in the range 2.699 (3)–2.892 (3) Å. The solvent CH2Cl2molecules reside in channels aligned along theaaxis and are connected to the complex molecules by C—H...O interactions.
