The title compound, bis[3,5-difluoro-2-(pyridin-2-yl)phenyl](4,4′-dimethoxy-2,2′-bipyridine)iridium(III) hexafluoridophosphate, is a distorted octahedral cyclometalated complex that exhibits a trans effect.

Abstract

The title cyclometalated distorted octahedral iridium complex, [Ir(C₁₁H₆F₂N)₂(C₁₂H₁₂N₂O₂)]PF₆, exhibits elongated Ir—N bonds to the dimethoxy bipyridine ligand [2.128 (3) and 2.136 (3) Å] where these nitrogen atoms are trans to the Ir—C bonds of the two cyclometalating difluorophenylpyridine ligands. The angles between the mean planes of the phenyl and pyridyl fragments within the individual ligands range from 3.5 (2) to 11.4 (2)° to deviate slightly from coplanarity.

Structure description

The title compound, [Ir(dfppy)₂(bipyOMe)](PF₆), is a distorted octahedral complex composed of bidentate cyclometallated ligands. The photophysical properties of cyclometalated iridium(III) complexes have been studied extensively in diverse applications such as cell imaging and OLEDs (Lee et al., 2009 ▸; Thorp-Greenwood, 2012 ▸; You et al., 2014 ▸). In [Ir(dfppy)₂(bipyOMe)](PF₆), the nitrogen atoms of the bipyOMe ligand are oriented trans to the carbon atoms of the dfppy ligands (Fig. 1 ▸). The Ir—N bond lengths to the bipyOMe ligand are 2.128 (3) and 2.136 (3) Å, longer than the Ir—N [2.035 (3) and 2.042 (3) Å] or Ir—C [2.014 (3) and 2.017 (3) Å] bonds to the dfppy ligands. This is consistent with a substantial trans effect directed by the carbon atoms of dfppy. This feature is also present in related structures in the literature, including for example Ir—N bonds to the trans-effected nitrogen atoms of the hydrogen pyridin-2-yl-phosophonato ligand of bis[3,5-difluoro-2-(pyridin-2-yl)phenyl](hydrogen pyridin-2-yl-phosphonato)iridium(III) [Ir—N = 2.153 (4) Å; Zeng et al., 2019 ▸], and of the bipyridine ligands in the structures of (2,2′-bipyridine)bis[3,5-difluoro-2-(pyridin-2-yl)phenyl]iridium(III) complexes [ranging from 2.120 (4) to 2.141 (4) Å; Li et al., 2017 ▸; Moriuchi et al., 2012 ▸]. This arrangement maximizes the number of C—Ir—N interligand trans-interactions compared to other potential isomers that would orient only one of the bipyOMe nitrogen atoms across from a strong trans-donor carbon atom, or that would have both strong trans-donor carbon atoms opposing one another (i.e. all nitrogen atoms are trans to one another).

The structures of the molecular components of the title compound shown as 50% probability ellipsoids. Hydrogen atoms have been omitted for clarity.

In addition to the octahedral distortion arising from the trans-effect, an angular distortion occurs from the chelating ligands, with cis-angles about iridium ranging from 76.39 (10) to 101.08 (12)°, and trans-angles about iridium ranging from 172.49 (12) to 177.11 (12)°. The ligands themselves deviate slightly from coplanarity, with mean plane to mean plane angles between the phenyl and pyridyl fragments within the individual ligands ranging from 3.5 (2) to 11.4 (2)°. The methyl groups of the bipyOMe ligands both fold inward. Neighboring complexes form dimers (Fig. 2 ▸) through interactions between their dfppy ligands, including offset π stacking [centroid–centroid = 3.616 (3) Å; plane-to-plane distance = 3.202 (3) Å] and C—H⋯π (H⋯centroid = 2.52 Å) interactions. Several C—H⋯F interactions between the complexes and the (PF₆)⁻ anions (Table 1 ▸, Fig. 3 ▸), as well as a C—H⋯O interaction between methoxy groups of neighboring complexes further support the long-range packing.

Dimers of the title complex formed *via* offset π stacking and C—H⋯π interactions. The projection is viewed along [010].

Synthesis and crystallization

[Ir(dfppy)₂Cl]₂ was prepared according to the literature (Skórka et al., 2016 ▸). [Ir (dfppy)₂Cl]₂ (0.0508 g, 0.0418 mmol) and 4,4′-dimethoxy-2,2′-bipyridine (0.0208 g, 0.0962 mmol) were combined in ethylene glycol (5 ml). The resulting yellow–green heterogenous mixture was heated under N₂ to 150°C while stirring_. After 20 h, the resulting yellow homogenous solution was allowed to cool to room temperature and 10 ml of NH₄PF₆ (sat. aq.) were added. The yellow precipitate that formed was collected by vacuum filtration, washed with H₂O (3 × 10 ml), Et₂O (3 ×10 ml), and dried in vacuo to give a yellow powder (0.0517 g, 78.3%). Yellow needle-like crystals suitable for X-ray diffraction were obtained by vapor–vapor diffusion from a solution of hexanes and dichloromethane. ¹H NMR (400 MHz, DMSO-d ₆) δ 8.48 (d, J = 2.7 Hz, 2H), 8.28 (d, J = 8.5 Hz, 2H), 8.03 (t, J = 7.9 Hz, 2H), 7.75 (dd, 2H), 7.65 (d, J = 6.4 Hz, 2H), 7.28 (td, 4H), 6.97 (d, J = 11.8 Hz, 2H), 5.61 (dd, 2H), 4.00 (s, 6H).

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. H atoms were placed in calculated positions with C—H bond distances of 0.95 Å for aromatic 0.98 Å for CH₃ moieties, respectively. Methyl H atoms were allowed to rotate but not to tip to best fit the experimental electron density. U_iso(H) values were set to a 1.5 (for CH₃) or 1.2 (for C—H) times U_eq(C).
