[6-(4-Bromo­phen­yl)-2,2′-bipyridine-κ² N,N′]bis­(triphenyl­phosphane-κP)copper(I) tetra­fluoridoborate

Abstract

The title compound, [Cu(C₁₆H₁₁BrN₂)(C₁₈H₁₅P)₂]BF₄, is composed of one Cu^I atom, one 6-(4-bromo­phen­yl)-2,2′-bipyridine (L) ligand, two triphenyl­phosphane mol­ecules and one tetra­fluoridoborate anion. The Cu^I ion is four-coordinated in a distorted tetra­hedral configuration by two N atoms from L and two P atoms from triphenyl­phosphane ligands. In the L ligand, the two pyridine rings are not coplanar; the mean planes making a dihedral angle of 15.3 (5)°. In the crystal, the ions are linked by weak C—H⋯F inter­actions.

Comment

Copper(I) complexes with diimine and phosphane ligands have attracted much attention for their rich photophysical properties and diversity coordination geometry (Engelhardt et al., 1985; Kirchhoff et al., 1985; Navarro et al., 2008; Wang et al., 2010). According to the size of diimine and phosphane ligands, these complexes can adopt three- and four-coordination modes around the metal center. Peng (2010) previously reported a three-coordinated copper(I) complex with 6-(4-bromo)phenyl-2,2'-bipyridine, here we report its related four-coordinated species.

The crystal structure of the title compound is depicted in Fig. 1. The Cu^I ion is four-coordinated in a distorted tetrahedral geometry by two N atoms from 6-(4-bromo)phenyl-2,2'-bipyridine (L) and two P atoms from triphenylphosphane molecules. The coordination bond angles around the Cu atom vary from 78.7 (3)° (N1—Cu1—N2) to 128.29 (9)° (P1—Cu1—P1). The two Cu—P bond distances of 2.265 (2) and 2.276 (2) Å are very similar while the Cu—N bond distance is slightly longer with the N atom of the substituted pyridine ring (2.178 (6) Å) than with the other one (2.095 (7) Å). These bond distances are within the normal ranges of related complexes (Engelhardt et al., 1985; Wang et al., 2010). In addition, the two pyridine rings in ligand L are not coplanar, the mean planes exhibit a dihedral angle of 15.3 (5) °. In the crystal, the ions are linked by weak C-H···F interactions (Table 1).

Experimental

The ligand 6-(4-bromophenyl)-2,2'-bipyridine (L) was prepared by a literature method (Wang et al., 2010). A mixture of [Cu(CH₃CN)₄]BF₄ (100 mg, 0.32 mmol) and L (99 mg, 0.32 mmol) in dichloromethane (20 ml) was stirred under nitrogen atmosphere at room temperature for 2 h. Then triphenylphosphane (170 mg, 0.64 mmol) was added kept stirring for 2 h. The solvents were removed and the solid residue was afforded. Yellow single crystals suitable for X-ray diffraction were obtained from the solution of dichloromethane by vapor diffusion with diethyl ether (yield: 82%). Analysis calculated for [Cu(C₁₆H₁₁N₂Br)(C₁₈H₁₅P)₂].(BF₄): C 63.29, H 4.19, N 2.84%; Found: C 63.38, H 4.03, 2.91%.

Refinement

All H atoms were positioned geomertrically and treated as riding with C—H = 0.93 Å and U_iso(H) = 1.2 U_eq(C).

Special details

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
