Crystal structure of fac-[2-(4-methyl-5-phenyl-pyridin-2-yl)phenyl-?2C1,N]bis-[2-(pyridin-2-yl)phenyl-?2C1,N]iridium(III).

ABSTRACT: In the title compound, [Ir(C11H8N)2(C18H14N)], the IrIII ion adopts a distorted octa-hedral coordination environment defined by three C,N-chelating ligands, one stemming from a 2-(4-phenyl-5-methyl-pyridin-2-yl)phenyl ligand and two from 2-(pyridin-2-yl)phenyl ligands, arranged in a facial manner. The IrIII ion lies almost in the equatorial plane [deviation = 0.0069?(15)?Å]. In the crystal, inter-molecular ?-? stacking inter-actions, as well as inter-molecular C-H?? inter-actions, are present, leading to a three-dimensional network.

Project description:In the title compound, [Ir(C11H8N)2(C13H10NO)]·CH2Cl2, the Ir(III) ion is six-coordinated by two C,N-bidentate 2-(pyridin-2-yl)phenyl ligands and one N,O-bidentate 2-[(phenyl-imino)-meth-yl]phenolate anion, giving rise to a distorted octa-hedral environment. The C,N-bidentate ligands, in which the C and N atoms are statistically disordered over two sites and therefore both pairs of C and N atoms are trans and cis relative to each other, are almost perpendicular to each other [the dihedral angle between the least-square planes is 87.00?(4)°]. An intra-molecular C-H?O hydrogen bond, as well as inter-molecular C-H?? inter-actions and ?-? inter-actions, contribute to the stabilization of the mol-ecular and crystal structure.

In the crystal, a combination of C-H⋯N and C-H⋯Cl hydrogen-bonding inter-actions connect the mol-ecules into a three-dimensional network.

Project description:The asymmetric unit of the solvated title complex, [Ir(C11H8N)2(C15H14NO3)]·2CH2Cl2, consists of two complex mol-ecules together with four di-chloro-methane solvent mol-ecules, one of which is disordered. In each complex mol-ecule, the IrIII ion has a distorted octa-hedral coordination environment defined by two 2-phenyl-pyridine ligands, through two phenyl C and two pyridine N atoms, and by one N,O-bidentate 2-[(2,4-di-meth-oxy-phenyl-imino)-meth-yl]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 mol-ecules. In both complex mol-ecules, the two 2-phenyl-pyridine 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, inter-molecular C-H⋯O inter-actions as well as inter-molecular C-H⋯π inter-actions are present, leading to a three-dimensional network structure. One of the four dichlormethane solvent mol-ecules shows disorder over two sets of sites [occupancy ratio 0.79 (2):0.21 (2)].

Crystal structure of fac-{5-[(hexyl-aza-nium-yl)meth-yl]-2-(pyridin-2-yl)phenyl-?2 N,C 1}bis-[2-(pyridin-2-yl)phenyl-?2 N,C 1]iridium(III) chloride.

Project description:The asymmetric unit of the title compound, fac-[Ir(C11H8N)2(C18H24N2)]Cl or fac-[Ir(ppy)2(Hppy-NC6)]Cl, contains two [Ir(ppy)2(ppy-NC6)](H+) cations, two Cl- anions and disordered solvent. In each complex mol-ecule, the IrIII ion is coordinated by two C,N-bidentate 2-(pyridin-2-yl)phenyl ligands and one C,N-bidentate N-[4-(pyridin-2-yl)benz-yl]hexan-1-aminium ligand, leading to a distorted fac-octa-hedral coordination environment. In the crystal, the mol-ecules are linked by N-H?Cl, C-H?? and ?-? inter-actions, forming a three-dimensional supra-molecular structure. The hexyl group of one mol-ecule is disordered over two orientations with a refined occupancy ratio of 0.412?(13):0.588?(13). The acetone and hexane solvent mol-ecules were found to be highly disordered and their contribution to the scattering was masked using the solvent-masking routine smtbx.mask in OLEX2 [Rees et al. (2005 ?). Acta Cryst. D61, 1299-1301]. These solvent mol-ecules are not considered in the given chemical formula and other crystal data.

These phospho-rescent cyclo-metallated iridium(III) compounds have been structurally investigated in order to better understand the nature of their blue-shifted emssions while maintaining high quantum yields. Compound 1 exhibits substantial twisting of the mesitylene rings out of the plane of the attached pyridine ring, with dihedral angles of 67.0?(1) and 78.7?(1)° between the best mean planes. For both compounds, the contribution of disordered solvent mol-ecule(s) was removed using the SQUEEZE [Spek (2015 ?). Acta Cryst. C71, 9-18] routine in PLATON [Spek (2015 ?). Acta Cryst. C71, 9-18]. These solvent mol-ecules are not considered in the given chemical formula and other crystal data.

Project description:In the title complex, [Ir(C11H8N)2(C6H5N2O)], the octa-hedrally coordinated Ir(III) atom is bonded to two 2-(pyridin-2-yl)phenyl ligands, through two phenyl C and two pydidine N atoms, and to one pyridine-2-aldoxime ligand through a pyridine N and an oxime N atom.

C-H?? inter-actions are also observed.
