Abstract top

The title compound, [Au(C26H30B10P2)(C26H30B9P2)]·0.5CH2Cl2·0.5H2O, contains two independent complex molecules in the asymmetric unit. The gold(I) centres display a distorted tetrahedral geometry. The complex is stablized through weak intramolecular [pi]-[pi] stacking (Cg...Cg = 4.17 Å) and edge-to-face interactions (H...Cg = 3.21 Å). Adjacent molecules interact through C-H...[pi] (H...Cg = 2.88 Å) and B-H...[pi] (H...Cg = 3.15 Å) contacts, forming a three-dimensional network, with solvent molecules occupying the cavities. One of the phenyl groups was disordered over two sites with occupancy factors of 0.65 and 0.35.

Comment top

We are currently investigating a wide variety of boron-containing ligands (Crossley et al., 2005; Todd et al., 2005; Ioppolo et al., 2007a, 2007b; Ching et al., 2007) for application as potential BNCT agents (Crossley et al., 2007). The title compound (I) was synthesized as part of these ongoing investigations. The gold(I) centre is bound to four phosphorus atoms from two ligands (one 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane and one 7,8-bis(diphenylphosphino)-7,8-dicarba-nido-undecaborane) giving an overall neutral charge to each molecule. The metal centre has a distorted tetrahedral geometry (Fig. 1), the distortion arising primarily from the small bite angle of the phosphorus containing ligands of less than 90 °. This arrangement is stabilized by intramolecular edge-to-face and offset face-to-face π-π interactions between the phenyl rings bound to each phosphorus ligand. There are further intermolecular π-π interactions present in the crystal lattice. Adjacent molecules connect via both edge-to-face π-π and phenyl-carborane interactions forming infinite two-dimensional sheets which propagate in the bc-plane. Indicative distances include C70H—B13 (2.86 Å), C102H—B38 (3.28 Å), C30H—C88 (2.88 Å) and C18H—C63 (3.17 Å). A schematic representation of part of one of these sheets is given in Fig. 2. These 2-D sheets interact with adjacent sheets through further BH - π and phenyl-phenyl contacts to form a 3-D motif, a schematic representation of which is shown in Fig. 3. These interactions are indicated by a B35H—C100 distance of 3.15 Å and a C24H—C70 distance of 3.53 Å.

Related literature top

The chelating P-donor ligand 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-carborane has been used to prepare 2-, 3- and 4-coordinate complexes of gold(I) (Crespo et al., 1992, 1994; Al-Baker et al., 1985). Coordination of this ligand has often led to deboronation of the closo-carborane cage to afford the corresponding nido-carborane in polar solvents (Teixidor et al., 1995, 1996). A non-solvated crystal structure of the title compound has been reported previously (Crespo et al., 1997). Facile deboronation of the carborane cage in polar solvents has also been observed when substituents α to the cage are electron withdrawing (Shaeck & Kahl, 1999; Ioppolo et al., 2007a,b). In contrast, our group has shown that ligands containing the thermodynamically stable 1,12-carborane cluster do not degrade upon complexation to gold(I) (Ioppolo et al., 2007a,b). Boron-containing ligands and their respective complexes are of interest for potential application in boron neutron capture therapy (BNCT) (Crossley et al., 2005, 2007; Todd et al., 2005; Ioppolo et al., 2007a,b; Ching et al., 2007). For the synthesis of the precursor gold compound, see: Uson et al. (1989).

Experimental top

The title compound was prepared from [AuCl(SMe2)] by using a modification of a previously reported method (Uson et al., 1989) and identified as the desired product by comparison with literature data (Crespo et al., 1997). Crystals suitable for X-ray diffraction were isolated from a CH2Cl2 solution after several days of slow evaporation.

Refinement top

C and B bound-H (except the bridging H present on the nido cages) atoms were included in idealized positions and refined using a riding-model approximation, with C—H = 0.95 - 0.99 Å and B—H = 1.12 Å. The bridging H atoms on the nido cages were located in the difference Fourier map prior and refined with bond length restraints of 1.10 (4) Å. Uiso(H) values were fixed at 1.2Ueq of the parent atoms. One of the phenyl rings is disordered and modelled over two positions with occupancies of 0.65 and 0.35, respectively. Rigid body restraints were employed on these rings to facilitate realistic modelling. The two water molecules are both half occupancy and were modelled isotropically. Despite being in almost ideal positions for hydrogen bonding, their H atoms could not be located in the difference Fourier map, and were not included in the model. The max. and min. electron density peaks were located 0.91 Å and 0.07 Å from the Au2 and C56B atoms, respectively.

Special details top

Experimental. The crystal was coated in Exxon Paratone N hydrocarbon oil and mounted on a thin mohair fibre attached to a copper pin. Upon mounting on the diffractometer, the crystal was quenched to 150(K) under a cold nitrogen gas stream supplied by an Oxford Cryosystems Cryostream and data were collected at this temperature.

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.
