[μ-4,5-Bis(diphenyl­phosphino)-9,9-di­methylxanthene]bis­[(trifluoro­acetato)gold(I)] and its dichloro­methane 0.58-solvate

The dinuclear Au^I complex containing the 4,5-bis­(diphenyl­phosphino)-9,9-dimethylxanthene (xantphos) ligand and trifluoro­acetate anions exists in a solvent-free form, [μ-4,5-bis­(diphenyl­phosphino)-9,9-dimethyl­xanthene]bis­[(trifluoro­acetato)gold(I)], [Au₂(C₂F₃O₂)₂(C₃₉H₃₂OP₂)], (I), and as a dichloro­methane solvate, [Au₂(C₂F₃O₂)₂(C₃₉H₃₂OP₂)]·0.58CH₂Cl₂, (II). The trifluoro­acetate anions are coordinated to the Au^I centres bridged by the xantphos ligand in both compounds. The Au^I atoms are in distorted linear coordination environments in both compounds. The phosphine substituents are in a syn arrangement in the xantphos ligand, which facilitates the formation of short aurophilic Au...Au inter­actions of 2.8966 (8) Å in (I) and 2.9439 (6) Å in (II).

S1. Comment

Coordination-directed self-assembly of metal centres and multidentate ligands has become a powerful technique for the preparation of large supramolecular structures of defined shapes and sizes (Levin & Stang, 2000). Among these compounds are the Au^I–diphosphine complexes, which have attracted much interest because of their photophysical, catalytic and pharmaceutical applications (Keefe et al., 2000). The 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene ligand (xantphos) was first structurally characterised by Hillebrand et al. (1995), and in recent years xantphos and its metal complexes have been used as effective catalysts (Kranenburg et al., 1995). The transition metal [rhodium(I), platinum(II), palladium(II), nickel(II)] complexes of the xantphos ligand are essential catalysts in hydroformylation, allylic alkylation, amination and hydrocyanation reactions (Kamer et al., 2001). The Au^I complex of xantphos, [AuCl(xantphos)], catalyses the dehydrogenative silylation of alcohols with high chemoselectivity and solvent tolerance (Ito et al., 2005).

The first Au^I–xantphos complexes of dinuclear [Au₂Cl₂(µ-xantphos)] and mononuclear [Au(xantphos)₂][SbF₆] were synthesised and structurally characterized a few years ago (Pintado-Alba et al., 2004). We recently reported the synthesis and structural characterization of two novel Au^I–xantphos complexes, [Au₂(NO₃)₂(µ-xantphos)] [the first example of the crystallization-induced spontaneous resolution of a dinuclear Au^I complex] and [Au₂(µ-xantphos)₂](NO₃)₂ (Deák et al., 2006). As a continuation of our work on Au^I complexes of xanthene-based diphosphine ligands, the dinuclear [Au₂(nixantphos)₂](NO₃)₂ [nixantphos = 4,6-bis(diphenylphosphino)phenoxazine] complex was synthesised and X-ray analysis revealed the solvent-assisted spontaneous resolution of the [Au₂(nixantphos)₂]²⁺ metallacycle (Tunyogi et al., 2008).

All reported dinuclear Au^I complexes with xantphos and nixantphos ligands exhibit short intramolecular aurophilic Au···Au interactions ranging from 2.856 (1) to 2.995 (1) Å (Deák et al., 2006; Pintado-Alba et al., 2004; Tunyogi et al., 2008). The Au···Au bond distance in complexes showing aurophilic interactions ranges from 2.70 to 3.30 Å (Schmidbaur, 2000). The strength of this attraction has been determined to be ca 7–11 kcal mol^-1 [1 kcal mol^-1 = 4.184 kJ mol^-1] and is comparable with that of hydrogen bonding (Schmidbaur et al., 1988). Very recently, the tricoordinate monomeric [AuCl(xantphos)] complex was prepared and structurally characterised (Ito et al., 2009). The mononuclear [Au(xantphos)₂][SbF₆] and [AuCl(xantphos)] complexes lack any additional aurophilic interactions (Ito et al., 2009; Pintado-Alba et al., 2004).

We report here the structures of a dinuclear Au^I complex containing the xantphos ligand and trifluoroacetate anions, in a solvent-free form, [Au₂(O₂CCF₃)₂(µ-xantphos)], (I), and as a dichloromethane solvate, [Au₂(O₂CCF₃)₂(µ-xantphos)].0.58CH₂Cl₂, (II). In both (I) and (II) the trifluoroacetate anions are coordinated to the Au^I centres bridged by the xantphos ligand (Figs. 1 and 2). In (I), the Au1 atom is disordered over two sites. The Au^I atoms are in distorted linear coordination environments in both compounds, with P—Au—O angles of 159.4 (5), 173.29 (15) and 174.1 (2)° in (I), and 168.40 (14) and 174.18 (14)° in (II). The deviation from linearity of the P—Au—O angles could be the result of an intramolecular aurophilic interaction (Mohamed et al., 2003). The Au^I atom has little affinity for O-donor ligands, and Au^I complexes containing Au—O bonds are generally used as precursors in gold chemistry (Brandys et al., 2000; Deák et al., 2007; Preisenberger et al., 1999).

Gold(I)–phosphine complexes containing the trifluoroacetate anion can be grouped into three broad categories, namely those having no aurophilic interactions, those with intermolecular Au···Au interactions, and those with intramolecular Au···Au interactions. Complexes in the first category, e.g. [Ph₃PAu(O₂CCF₃)], are mononuclear and contain a monophosphine ligand with bulky substituents on P, and the formation of an Au···Au interaction is precluded by steric restraints (Zhang et al., 1988). Gold(I) compounds in the second category contain either monophosphine or diphosphine ligands. Complexes of monophosphine ligands, e.g. [Me₃PAu(O₂CCF₃)], form trimers via intermolecular Au···Au interactions when the substituents on P are not too bulky (Preisenberger et al., 1999). Complexes of diphosphine ligands having phosphine substituents linked by conformationally flexible backbones, e.g. [Au₂(O₂CCF₃)₂(µ-dppb)] [dppb = 1,4-bis(diphenylphosphino)butane] (Brandys et al., 2000) and [Au₂(O₂CCF₃)₂(µ-dppf)] [dppf = 1,1'-bis(diphenylphosphino)ferrocene] (Low et al., 1997), also exhibit intermolecular Au···Au interactions. In these compounds, the formation of any intramolecular aurophilic interaction is precluded by the anti arrangement of the phosphine substituents. Gold(I) complexes in the third category exhibit intramolecular Au···Au interactions as a result of their rigid phosphine backbone, which preorganizes the Au^I centres in a syn configuration. In the [Au₂(O₂CCF₃)₂(µ-dppbz)] [dppbz = 1,2-bis(diphenylphosphino)benzene] complex, the rigid backbone of the diphosphine advances the formation of an intramolecular aurophilic interaction of 2.908 (1) Å (Deák et al., 2007). Complexes (I) and (II) also exhibit short aurophilic interactions of 2.8966 (8) Å in (I) and 2.9439 (6) Å (II). In (I) and (II) the xantphos ligand backbone is folded and tilted [by 53.9 (1)° in (I) and 52.8 (1)° in (II)] with respect to the main Au···Au axis, most likely to accommodate the two Au^I atoms at a close distance.

The Au–P bond lengths are 2.2208 (19) and 2.2113 (18) Å in (I), and 2.2133 (16) and 2.2202 (17) Å in (II). The observed P1···P2 distances in (I) [4.687 (2) Å] and (II) [4.742 (2) Å] are significantly longer than that in the free ligand [4.045 (1) Å; Hillebrand et al., 1995]. The trifluoroacetate ions in both (I) and (II) coordinate to the Au^I atom through only one O atom, with Au—O = 2.060 (5) and 2.100 (7) Å in (I), and 2.071 (5) and 2.094 (5) Å in (II). For comparison, in the acetate structure [Ph₃PAu(O₂CMe)] (Jones, 1984) the Au—O distance is 2.063 (6) Å.

In (I) and (II), the orientation of the coordinated trifluoroacetate anions can be defined by the values of the O2—Au1—Au2—O4 torsion angles [-74.2 (3) in (I) and -67.6 (2)° (II)]. In both complexes, the CF₃ group has high thermal motion consistent, with some unresolved rotational disorder, as is often found in other trifluoroacetate compounds (Kia et al., 2005; Rodrigues et al., 2000, 2001). In (II), the anisotropic displacement parameters of atoms O3 and C17 atoms are also large, however the data quality did not enable to develop an adequate model for this possible disorder of the trifluoroacetate group.

A variety of dinuclear Au^I–diphosphine complexes have been reported to be luminescent in solution and in the solid state under ambient conditions (King et al.,1989; Pawlowski et al.,2004; Pintado-Alba et al., 2004). Complex (I) is nonemissive in dichloromethane solution at room temperature. The solid-state emission spectrum of (I) at room temperature exhibits a broad band at 416 nm and two shoulders at 450 and 560 nm, when excited at 340 nm. [Corresponding data for (II)?]

S2. Experimental

Compound (I) was prepared starting from [Au₂Cl₂(µ-xantphos)] (Deák et al., 2006). A solution of [Au₂Cl₂(µ-xantphos)] (1 mmol) in dichloromethane (20 ml) was added to a suspension of silver(I)? trifluoroacetate (2 mmol) in dichloromethane (5 ml). After stirring for 45 min shielded from light, the AgCl precipitate was filtered through Celite. To the colourless filtrate, diethyl ether (10 ml) was added, and shiny crystals of (I) were obtained by slow evaporation of this solution.

Crystals of (II) were obtained by layering the filtrate with n-hexane. Shiny crystals of (I) and (II) were collected by filtration, washed with n-hexane and dried under vacuum. [How were the two compounds separated?] Absorption–emission and excitation data for (I) (Hitachi F-2500 fluorescence spectrophotometer, nm): 280 and 340 (CH₂Cl₂, 10^-5 M at room temperature); λ_ex = 340 nm, λ_max (nm) = 416 (br), 450 (sh), 560 (sh); λ_em = 420 nm, λ_max (nm) = 270, 315 (sh) (solid, room temperature).

S3. Refinement

In complex (I), the disorder of atom Au1 was refined over two positions using an EADP constraint (SHELXL97; Sheldrick, 2008) [refined site-occupancy factors are 0.834 (8) and 0.166 (8)]. The carboxylic acid atoms O3 and C16 were also determined to be disordered over two positions. Between the disordered components [refined site-occupancy factors are 0.65 (3) and 0.35 (3)], all equivalent C—O and C—C distances were restrained to be equal. The displacement parameters for atoms C161 and C162 atoms were also constrained using EADP constraints. Planarity was also restrained for the disordered C17/C161/O2/O31 and C17/C162/O2/O32 carboxyl systems. The anisotropic displacement parameters of atoms C14 and C15 are large for methyl C atoms, which may be due to large thermal motion and/or disorder.

In (II), the dichloromethane solvent molecule was not sufficiently resolved in the electron-density map, and therefore it could not be modelled with disordered atoms. Accordingly, the residual electron density was removed using the SQUEEZE routine in PLATON (Spek, 2009). The total volume available for solvent molecules was 529 ų, which is distributed over four voids. The residual electron count was 97 electrons per unit cell, which corresponds to 2.31 dichloromethane molecules per unit cell. This means that 0.58 of a dichloromethane molecule could be accommodated in each void.

The methyl H atoms were constrained to an ideal geometry (C—H = 0.96 Å), with U_iso(H) = 1.5U_eq(C), but were allowed to rotate freely about their C—C bonds. All remaining H atoms were placed in geometrically idealized positions (C—H = 0.93 Å), and constrained to ride on their parent atoms with U_iso(H) = 1.2U_eq(C).

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. 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.

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. 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.

The dichloromethane solvent molecule was not sufficiently resolved in the electron density map, therefore it could not be modelled with disordered atoms. Accordingly, the residual electron density was modelled using the SQUEEZE routine in PLATON (Spek, 2009). The total volume available for solvent molecules is 529 ų, distributed over four voids. The residual electron count was 97 e/unit cell, which corresponds to 2.31 of dichloromethane / unit cell, which means that 0.58 of dichloromethane molecule could be accommodated in each void.
