Crystal structure and luminescent properties of bis­26-dimethyl-3-(pyridin-2-yl-κN)pyridin-4-yl-κC4(2266-tetra­methylhepta­ne-35-dionato-κ2OO′)iridium(III) ethyl acetate monosolvate

摘要

In the solvated title compound, [Ir(C12H11N2)2(C11H19O2)]·CH3CO2C2H5, the Ir^III ion adopts a distorted octa­hedral coordination environment resulting from its coordination by two C,N-chelating 2,6-dimethyl-3-(pyridin-2-yl)pyridin-4-yl ligands and one O,O′-chelating 2,2,6,6-tetra­methylhepta­ne-3,5-dionate ligand. The C,N-chelating ligands are perpendicular to each other [dihedral angle between the least-squares planes = 87.86 (5)°] and are arranged in a cis-C,C′ and trans-N,N′ fashion. In the crystal, pairwise C—H⋯π inter­actions between inversion-related Ir^III complexes are present, forming a dimeric structure. The title complex shows bright bluish–green emission with good quantum efficiency in solution at room temperature.
