Bis[μ-1,3-bis­(di­phenyl­phosphan­yl)propane-κ²P:P′]digold(I) tetra­chloridonickelate(II) diethyl ether monosolvate

The title compound, [Au₂(C₂₇H₂₆P₂)₂][NiCl₄]·C₄H₁₀O, consists of a digold(I) complex cation, an [NiCl₄]²⁻ complex anion and a diethyl ether solvent mol­ecule. Two 1,3-bis­(di­phenyl­phosphan­yl)propane (dppp) ligands bridge two Au^I atoms, forming a metallacycle in which each of the Au^I atoms is coordinated in a slightly distorted linear environment by two P atoms. In the complex anion, the Ni^II atom is coordinated by four chloride ligands in a distorted tetra­hedral geometry. The complex cation and the complex anion form a cation–anion pair through two Au...Cl contacts of 3.040 (1) and 3.021 (2) Å. One of the phenyl groups of the dppp ligand is disordered over two positions with equal occupancies.

S1. Comment

In recent years, diphosphine-bridged cyclic digold(I) complexes have attracted considerable attention because of their intriguing photophysical properties that originate from the presence of an aurophilic interaction between gold(I) ions. A typical example is [Au₂(dppm)₂]²⁺ (dppm = bis(diphenylphosphanyl)methane), which is easily prepared from dppm having a methylene linker between two P atoms, in combination with an Au^I ion. Analogous digold(I) complexes having a longer linker between two P atoms, such as 1,2-bis(diphenylphosphanyl)ethane (dppe) and 1,3-bis(diphenylphosphanyl)propane (dppp), have also been prepared, but only a few of them have been structurally characterized to date (Allen, 2002).

Recently, we started to investigate the creation of diphosphine-bridged digold(I) metalloligands and their coordination behavior toward various metal ions, with the aim of the rational construction of heterometallic multinuclear and metallosupramolecular structures (Lee et al., 2012; Igashira-Kamiyama et al., 2012; Hashimoto et al., 2010). In the course of this study, we found the formation of a diphosphine-bridged digold(I) complex, [Au₂(dppp)₂]²⁺ (dppp = 1,3-bis(diphenylphosphanyl)propane), which is cocrystallized with [NiCl₄]^2– to give single-crystals of [Au₂(dppp)₂][NiCl₄].Et₂O (I). Here, we report the synthesis and crystal structure of (I).

Treatment of [Au₂Cl₂(dppp)] (Mirabelli et al., 1987) with 1 equiv of N,N'-ethylene-bis-D-penicillamine (Howard-Lock et al., 1986; Blondeau et al., 1967) in ethanol/water in the presence of KOH gave a white powder. When this powder was reacted with NiCl₂.6H₂O in ethanol, blue needle crystals of [Au₂(dppp)₂][NiCl₄].Et₂O (I) were obtained by the vapor diffusion of diethylether into the reaction solution.

Compound (I) crystallized in a centrosymmetric space group P2₁/n, which contains one digold(I) complex cation, one nickel(II) complex anion and one solvate diethylether molecule in the asymmetric unit. The complex cation has a cyclic digold(I) structure in [Au₂(dppp)₂]²⁺, in which two dppp ligands bridge two Au^I atoms. Each Au^I atom adopts a slightly distorted linear geometry (176.68 (5)°, 177.98 (5)°) coordinated by two P atoms from two different dppp ligands (Fig. 1). The Au–P bond distances (2.3013 (13)–2.3129 (13) Å) are within the range observed for [Au₂(dppp)₂]₂[Mo₈O₂₆], [Au₂(dppp)₂]₂[PMo₈O₂₆] and [Au₂(dppp)₂](CF₃CO₂)₂ (Au–P = 2.271–2.324 Å) (Gruber et al., 2010; Brandys et al., 2001). In the complex-cation of (I), two Au^I atoms and four P atoms are deviated from co-planarity, with the dihedral angle between two Au₂P₂ planes being 21.94 (2)°. This structural feature is different from those found in [Au₂(dppp)₂]₂[Mo₈O₂₆], [Au₂(dppp)₂]₂[PMo₈O₂₆] and [Au₂(dppp)₂](CF₃CO₂)₂, in which all the Au^I and P atoms in each complex-cation are located nearly on the same plane (Gruber et al., 2010; Brandys et al., 2001). The distance between two Au^I atoms in [Au₂(dppp)₂]²⁺ is 5.5424 (4) Å, indicative of the absence of an aurophilic interaction. In (I), a nickel(II) complex-anion, [NiCl₄]^2–, which has a distorted tetrahedral geometry, coexists with [Au₂(dppp)₂]²⁺ to balance the total charge. Note that [Au₂(dppp)₂]²⁺ and [NiCl₄]^2– are connected to each other through two Au···Cl bonding interactions (3.040 (1) Å and 3.021 (2) Å), while any other significant intermolecular interactions do not exist in (I) (Fig. 2).

S2. Experimental

To a white suspension containing 0.15 g (0.17 mmol) of [Au₂Cl₂(dppp)] in 300 ml of EtOH was added 0.056 g (0.17 mmol) of N,N'-ethylene-bis-D-penicillamine dissolved in 3 ml of a 0.1 M KOH aqueous solution. The mixture was stirred at room temperature for 3 h. The resulting colorless solution was evaporated to dryness, and then the residue was washed with H₂O to give a white powder (0.15 g). When 2.5 mg (0.01 mmol) of NiCl₂.6H₂O was added to a suspension of this white powder (10 mg) in 1 ml of EtOH, followed by stirring at room temperature for 3 h, a clear red orange solution was obtained. Vapor diffusion of diethylether into the resulting red orange solution afforded a small amount of blue needle crystals of [Au₂(dppp)₂][NiCl₄].Et₂O.

S3. Refinement

H atoms were placed at calculated positions [C–H = 0.99 (methylene) or 0.95 Å (phenyl)] and refined as riding with U_iso(H) = 1.2U_eq(C). One phenyl ring is disordered over two positions (C7–C12 and C13–C18) with site occupancies of 0.5. The FLAT and SIMU restraints were used to model the disordered phenyl ring.

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.
