Crystal structure of {(E)-2-[(3,4-dimethoxyphenylimino)methyl]phenolato-kappa N-2,O-1}bis[2-(pyridin-2-yl)phenyl-kappa C-2(1),N]iridium(III) dichloromethane disolvate

초록

The asymmetric unit of the solvated title complex, [Ir(C11H8N)(2)(C15H14NO3)]center dot 2CH(2)Cl(2), consists of two complex molecules together with four dichloromethane solvent molecules, one of which is disordered. In each complex molecule, the Ir-III ion has a distorted octahedral coordination environment defined by two 2-phenylpyridine ligands, through two phenyl C and two pyridine N atoms, and by one N,O-bidentate 2-[(2,4-dimethoxyphenylimino)methyl]phenolate anion. The Ir-III ions lie almost in the equatorial planes with deviations of 0.0396 (17) and 0.0237 (17) angstrom, respectively, for the two complex molecules. In both complex molecules, the two 2-phenylpyridine ligands are nearly perpendicular to each other [dihedral angles between the least-squares-planes of 89.91 (11) and 85.13 (11)degrees]. In the crystal, intermolecular C H center dot center dot center dot O interactions as well as intermolecular C-H center dot center dot center dot pi interactions are present, leading to a three-dimensional network structure. One of the four dichlormethane solvent molecules shows disorder over two sets of sites [occupancy ratio 0.79 (2):0.21 (2)].
