Comment top

Gold(I) forms an almost linear complex with a P—Au—Cl angles of 179.22 (4) °. The Au—Au distance of the complex is 3.131 (5) Å and is intramolecular. This is well within the range of aurophilic interactions as discribed by Holleman et al. as being normally between 2.7 Å and 3.4 Å. Other bond lengths are within expected ranges.

The molecule readilly crystalizes out of tetrahydrofuran (THF) and also includes this solvent in the crystal lattice. The molecule exhibits columns of head-to-tail complexes forming channels filled with THF. Intermolecular short contacts of 2.822 Å and 2.835 Å are displayed between Cl and H(1a) and Cl and H(14), respectively (Figure 2). The Cl—H(1a) interaction can be seen on the head-to-tail arranged complexes in a column between chlorines and adjacent hydrogen atoms situated on the ethyl substituted hydrazine bridge. The Cl—H(14) interaction occurs between chlorines and H atoms situated on a phenyl ring in close proximity. Hydrogen bonding distances between the THF O(1) atom and H(1 b) and H(22) are observed to be 2.553 Å and 2.698 Å, respectively.

Experimental top

Tetrahydrothiophenegold(I) chloride [(THT)AuCl] was suspended in THF. 0.5 equivalents of the ligand bis(diphenylphosphino)-1,2-diethylhydrazine dissolved in dichloromethane (DCM) was added to the stirred suspension. The suspension turned yellow and became clear and after a short time micro crystals started to form. Crystals of the molecule was obtained by halting stirring as soon as the reaction turned clear, crystals big enough for single-crystal X-Ray analysis formed overnight.

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.
