Synthesis, crystal structure and Hirshfeld surface analysis of [bis-(di-phenyl-phosphan-yl)methane-κP]chloridobis-[2-(pyridin-2-yl)phenyl-κ² N,C ¹]iridium(III).

ABSTRACT: The title Ir^III complex, [Ir(C₁₁H₈N)₂Cl(C₂₅H₂₂P₂)], was synthesized from the substitution reaction between the (ppy)₂Ir(μ-Cl)₂Ir(ppy)₂ (ppy = deprotonated 2-phenyl-pyridine, C₁₁H₈N^-) dimer and 1,1-bis-(di-phenyl-phosphan-yl)methane (dppm, C₂₅H₂₂P₂) under an argon gas atmosphere for 20 h. The Ir^III atom is coordinated by two C,N-bidentate ppy anions, a unidentate dppm ligand and a chloride anion in a distorted octa-hedral IrC₂N₂PCl arrangement. The N donor atoms of the ppy ligands are mutually trans while the C atoms are cis. Intra-molecular aromatic π-π stacking between the phenyl rings of ppy and dppm, and C-H⋯Cl inter-actions are observed. In the crystal, C-H⋯Cl and C-H⋯π contacts link the mol-ecules into a three-dimensional network. A Hirshfeld surface analysis was carried out to further qu-antify the inter-molecular inter-actions, and indicated that H⋯H contacts (63.9%) dominate the packing.

Crystal structure of mer-tris-{2,6-di-fluoro-3-[5-(2-fluoro-phen-yl)pyridin-2-yl-κN]pyridin-4-yl-κC4}iridium(III) di-chloro-methane hemisolvate n-hexane hemisolvate.

Project description:The asymmetric unit of the title compound, [Ir(C17H11F2N2)3]·0.5CH3(CH2)4CH3·0.5CH2Cl2, comprises one IrIII atom, three 2,6-di-fluoro-3-[5-(2-fluoro-phen-yl)pyridin-2-yl]pyridin-4-yl ligands and half each of an n-hexane and a di-chloro-methane solvent mol-ecule located about crystallographic inversion centres. The IrIII atom displays a distorted octa-hedral coordination geometry, having three C,N-chelating 2,6-di-fluoro-3-[5-(2-fluoro-phen-yl)pyridin-2-yl]pyridin-4-yl ligands arranged in a meridional manner. The IrIII ion lies almost in the equatorial plane [deviation = 0.0069 (15) Å]. The average distance [2.041 (3) Å] of Ir-C bonds is slightly shorter than that [2.076 (3) Å] of Ir-N bonds. A variety of intra- and inter-molecular C-H⋯F and C-H⋯π hydrogen bonds, as well as inter-molecular C-F⋯π inter-actions, contribute to the stabilization of the mol-ecular and crystal structures, and result in the formation of a two-dimensional network parallel to the ab plane. No inter-actions between n-hexane solvent mol-ecules and the other components in the title compound are observed.

Project description: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.

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.

Crystal structure of {(E)-2-[(phenyl-imino)-meth-yl]phenolato-?(2) N,O}bis-[2-(pyridin-2-yl)phenyl-?(2) C (1),N]iridium(III) di-chloro-methane monosolvate.

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.

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)].

[1,4-Bis(di-phenyl-phosphan-yl)butane-κ(2) P,P']di-bromido-palladium(II).

Project description:In the title complex, [PdBr2(C28H28P2)], the Pd(II) ion has a distorted cis-Br2P2 square-planar coordination geometry defined by two P atoms from the chelating 1,4-bis-(di-phenyl-phosphan-yl)butane ligand and two Br(-) anions. The four phenyl rings are inclined to the least-squares plane of the PdBr2P2 unit [maximum deviation = 0.1294 (7) Å], making dihedral angles of 66.3 (2), 87.2 (2), 68.8 (2) and 86.8 (2)°. The butyl-ene chain is in a gauche conformation, with a C-C-C-C torsion angle of 57.0 (8)°. Inter-molecular C-H⋯Br hydrogen bonds link the complex mol-ecules into supra-molecular layers in the ab plane. Weak π-π inter-actions, both intra- and inter-molecular [shortest inter-centroid distance = 4.598 (5) Å], are also noted in the three-dimensional architecture.

Synthesis, crystal structure and photophysical properties of chlorido-[2-(2',6'-di-fluoro-2,3'-bipyri-din-6-yl-κN 1)-6-(pyridin-2-yl-oxy-κN)phenyl-κC 1]platinum(II).

Project description:The title compound, [Pt(C21H12F2N3O)Cl], crystallizes with two crystallographically independent mol-ecules (A and B) in the asymmetric unit, which adopt similar conformations. The PtII atoms in both mol-ecules adopt distorted square-planar geometries, coordinated by one C and two N atoms from the tridentate 2',6'-di-fluoro-6-[3-(pyridin-2-yl-oxy)phen-yl]-2,3'-bi-pyridine ligand and a chloride anion: the C and Cl atoms are trans. In the crystal, C-H⋯Cl/F hydrogen bonds, F⋯π and weak π-π stacking inter-actions between adjacent A and B mol-ecules and between pairs of inversion-related B mol-ecules lead to the formation of a two-dimensional supra-molecular network lying parallel to the ab plane. The sheets are stacked along the c-axis direction and linked by F⋯π and weak π-π stacking inter-actions between pairs of inversion-related A mol-ecules, forming a three-dimensional supra-molecular network. The photoluminescence quantum efficiency of the title compound in the blue-green region of the visible region (λmax = 517 and 544 nm) is estimated to be ∼0.2-0.3, indicating that the title compound could be a suitable candidate as the emitting material in organic light-emitting diode (OLED) applications.
