摘要

The asymmetric unit of the solvated title complex, [Ir(C11H8N)2(C15H14NO3)]·2CH2Cl2, consists of two complex mol­ecules together with four di­chloro­methane solvent mol­ecules, one of which is disordered. In each complex mol­ecule, the IrIII 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 IrIII ions lie almost in the equatorial planes with deviations of 0.0396 (17) and 0.0237 (17) Å, 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)°]. In the crystal, inter­molecular C—H⋯O inter­actions as well as inter­molecular C—H⋯π 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)].
