[μ₂-Bis(diphenyl­phosphanyl)methane][μ₃-bis­(diphenyl­phosphanyl)meth­yl]trichlorido­tetra­gold(I) tetra­hydro­furan disolvate

Abstract

The title tetra­nuclear complex, [Au₄(C₂₅H₂₁P₂)Cl₃(C₂₅H₂₂P₂)]·2C₄H₈O, features two non-equivalent Ph₂PCPPh₂ fragments, one of which represents the ‘complete’ mol­ecule (with two H atoms at the central C atom); each of the two P atoms of this mol­ecule is coordinated by an Au atom [Au—P = 2.2256 (13) and 2.2710 (13) Å], and these two Au atoms form an Au—Au bond [3.2945 (3) Å], thus closing the five-membered Au₂P₂C ring. The first of these Au atoms has a terminal chlorido ligand [Au—Cl = 2.2806 (12) Å], whereas the second Au atom forms a covalent bond with the central C atom of the bis­(diphenyl­phosphino)methyl group [Au—C = 2.114 (5) Å]; the latter group in turn coordinates with its P atoms the gold atoms of the Cl–Au–Au–Cl group [Au—P = 2.2356 (13) and 2.2338 (13), Au—Au = 3.3177 (3), Au—Cl = 2.3091 (12) and 2.2950 (13) Å], thus closing the second Au₂P₂C ring. The two such rings have different chemical functions, but both exhibit envelope conformations. However, the first (with different substituents at the Au atoms) is non-symmetrical with one of the P atoms in the flap position of the envelope; the other one has a conformation with mirror symmetry, and the gold-substituted C atom is displaced by 0.740 (5) Å from the almost exactly planar (r.m.s. deviation = 0.0038 Å) Au₂P₂ group.

Comment

The crystal structures of Au compounds with the bis(diphenylphosphanyl)methane ligand have been widely studied (see, for instance, Bruce et al., 2006; Feng et al., 1997; Sevillano et al., 2007). Herein, we report the bis(tetrahydrofurane) solvate of a new tetranuclear complex with this ligand and a rather peculiar non-symmetrical structure.

The molecule of the title compound, (Fig. 1) features two chemically different fragments derived from bis(diphenylphosphanyl)methane, one of which represents neutral molecule coordinated to two gold atoms through each of its P atoms [Au3-P3 2.2710 (13), Au4-P4 2.2256 (13) Å]. These gold atoms are bonded to each other [Au3-Au4 3.2945 (3) Å] thus closing the Au₂P₂C-ring. The Au4 atom also has a terminal chloro ligand [Au4-Cl4 2.2806 (12) Å], whereas the Au3 atom is bonded to the C13 atom belonging to the bis(diphenylphosphanyl)methyl group [Au3-C13 2.114 (5) Å], which in its turn has each of its phosphorus atoms P1 and P2 bonded to gold atoms of the Cl1-Au1-Au2-Cl2 fragment [Au1-P1 2.2356 (13) Å, Au2-P2 2.2338 (13) Å, Au1-Au2 3.3177 (3) Å, Au1-Cl1 2.3091 (12) Å, Au2-Cl2 2.2950 (13) Å], thus closing the second five-membered ring. Both five-memebered Au₂P₂C rings have envelope conformations, however the conformation of symmetrically substituted ring with Au1 and Au2 atoms has a mirror symmetry [displacement of the C13 atom from the almost exactly planar Au₂P₂ group being 0.740 (5) Å], whereas the second five-membered ring is not symmetrical with one of the phosphorus atoms (P3) in the flap position, its displacement from the plane of the rest of the atoms in this ring being 0.889 (1) Å.

Experimental

A solution of AuCl (0.1 mmol, 23.5 mg) in 1 ml of H₂O and bis(diphenylphosphanyl)methane (0.2 mmol, 77 mg) in 1 ml of THF were mixed and sealed in a 4 ml glass vial and kept at 333 K for 2 days. Then the mixture was cooled down to room temperature and was allowed to stand. After 5 days, colorless crystals suitable for the X-ray diffraction experiment were collected.

Refinement

All H atoms were placed geometrically (C-H 0.95 Å and 0.99 Å for aromatic and methylene H atoms respectively) and treated as riding with U_iso(H) = 1.2U_eq(C). There are four residual peaks higher than 1 eÅ^-3, each one in the vicinity of each of the Au atom at the distances of 0.881-0.991 Å.

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 > 2sigma(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.
