The binuclear title compound, [Au2Fe(C9H10NOS)2(C17H14P)2]·CH2Cl2, which has the Fe atom located on a crystallographic centre of inversion, crystallizes as a 1:1 dichloromethane solvate, which is disordered about a centre of inversion. There is a small deviation from linearity defined by the SP donor set [S1—Au—P1 angle is 175.35 (5) °] which is due to an intramolecular Au⋯O contact [3.080 (5) Å]. The primary intermolecular contacts between binuclear molecules are of the type C—H⋯π, and are arranged so as to form columns in the a-axis direction in which the disordered solvent molecules reside.

Compound (I) was prepared following the standard literature procedure from the reaction of dppf(AuCl)2 and EtOC(═S)N(H)Ph in the presence of base (Hall et al., 1993). Crystals were obtained from the slow evaporation of a dichloromethane solution.
The H atoms were geometrically placed (C—H = 0.94-0.98 Å) and refined as riding with Uiso(H) = 1.2-1.5Ueq(C). The maximum and minimum residual electron density peaks of 2.84 and 1.47 e Å-3, respectively, were located within the C21–C26 ring (0.95 Å from the C21 atom) and 0.58 Å from the Cl1 atom, respectively. The binuclear molecule co-crystallised with a disordered dichloromethane solvent molecule. This was modelled over a centre of inversion with a full weight chloride and half-weight methylene group. The C and Cl atoms were treated with the ISOR command in SHELXL-97 to impose isotropic character to the anisotropic displacement parameters (Sheldrick, 2008). The following reflections (0,1,0), (0,-1,1) and (0,0,1) were omitted in the final
as they were obscured by the beamstop.The dppf (where dppf is the bidentate phosphine, [Ph2P(C5H4)]2Fe) derivatives of phosphinegold(I) thiocarbamides, of interest owing to crystal engineering and luminescence studies (Ho et al. 2006; Ho & Tiekink, 2007; Kuan et al., 2008), are comparatively rare. Thus, only three examples of dppf{Au[SC(OR)═NR']}2 have been described, i.e. R = Me & R' = PhNO2-4 (Ho et al., 2006), R = iPr & R' = PhNO2-4 (Ho & Tiekink, 2009), and R = iPr & R' = PhMe-4 (Tadbuppa & Tiekink, 2009). In the present report, the of the R = Et & R' = H derivative, (I), is described.
The dinuclear molecule has ═N1 bond, shows the expected characteristics. The magnitudes of the C1—S1 and C1═N1 bond distances of 1.755 (6) and 1.277 (8) Å, respectively, confirm that the anion is coordinating as a thiolate ligand. The overall conformation of the molecule is "open" in that the thiocarbamate ligands are lying on either side of the molecule, as found in the structure of the R = iPr & R' = PhMe-4 derivative (Tadbuppa & Tiekink, 2009) but contrasts the situation in each of dppf{Au[SC(OR)═ NC6H4NO2-p]}2, for R = Me (Ho et al., 2006) and i-Pr (Ho & Tiekink, 2009), whereby the molecule has a U-shaped conformation allowing for the formation of intramolecular Au···Au interactions.
with the Fe atom lying on an inversion centre, Fig. 1. The dinuclear molecule crystallises with a solvent dichloromethane molecule which is disordered about a centre of inversion, Fig. 1. The gold atom exists in the expected linear geometry defined by a SP donor set, Table 1, and the deviation from linearity [S1–Au–P1 is 175.35 (5) °] is ascribed to the close approach of the O1 atom, Au···O = 3.080 (5) Å. The anion, with a Z configuration about the C1In the π, Table 1. These are arranged so as to define columns along the a direction in which reside the solvent dichloromethane molecules.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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 dppf (where dppf is the bidentate phosphine, [Ph2P(C5H4)]2Fe) derivatives of phosphinegold(I) thiocarbamides, of interest owing to crystal engineering and luminescence studies (Ho et al. 2006; Ho & Tiekink, 2007; Kuan et al., 2008), are comparatively rare. Thus, only three examples of dppf{Au[SC(OR)═NR']}2 have been described, i.e. R = Me & R' = PhNO2-4 (Ho et al., 2006), R = iPr & R' = PhNO2-4 (Ho & Tiekink, 2009), and R = iPr & R' = PhMe-4 (Tadbuppa & Tiekink, 2009). In the present report, the crystal structure of the R = Et & R' = H derivative, (I), is described.
The dinuclear molecule has crystallographic symmetry with the Fe atom lying on an inversion centre, Fig. 1. The dinuclear molecule crystallises with a solvent dichloromethane molecule which is disordered about a centre of inversion, Fig. 1. The gold atom exists in the expected linear geometry defined by a SP donor set, Table 1, and the deviation from linearity [S1–Au–P1 is 175.35 (5) °] is ascribed to the close approach of the O1 atom, Au···O = 3.080 (5) Å. The anion, with a Z configuration about the C1═N1 bond, shows the expected characteristics. The magnitudes of the C1—S1 and C1═N1 bond distances of 1.755 (6) and 1.277 (8) Å, respectively, confirm that the anion is coordinating as a thiolate ligand. The overall conformation of the molecule is "open" in that the thiocarbamate ligands are lying on either side of the molecule, as found in the structure of the R = iPr & R' = PhMe-4 derivative (Tadbuppa & Tiekink, 2009) but contrasts the situation in each of dppf{Au[SC(OR)═ NC6H4NO2-p]}2, for R = Me (Ho et al., 2006) and i-Pr (Ho & Tiekink, 2009), whereby the molecule has a U-shaped conformation allowing for the formation of intramolecular Au···Au interactions.
In the crystal structure of (I), the primary interactions between the dinuclear molecules are of the type C–H···π, Table 1. These are arranged so as to define columns along the a direction in which reside the solvent dichloromethane molecules.
