Source of material

NaOH (Merck; 0.020 g, 0.50 mmol) in water (5 mL) was added to a suspension of (dppf)(AuCl)2 (0.255 g, 0.25 mmol) in acetonitrile (20 mL), followed by addition of iPrOC(=S)N(H)C6H4Cl-4 (0.115 g, 0.50 mmol) in dichloromethane (20 mL). After stirring for 3 h, the solution was left for slow evaporation at room temperature, yielding yellow crystals after 3 weeks. Yield: 0.278 g (79%).

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.95–1.00 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The maximum and minimum residual electron density peaks of 1.15 and 1.02 eÅ−3, respectively, were located 0.99 Å and 0.66 Å, respectively, from the Au atom.

Comment

The original interest in binuclear phosphane gold(I) thioamide molecules of the formula dppf{Au[SC(OR)=NC6H4Y-4]}2 related to an investigation of the solid-state photoluminescent properties of the R = Me and Y = NO2 derivative, isolated as a di-chloroform solvate [5]; dppf is 1,1′-bis(diphenylphosphino)ferrocene. Subsequently, crystal structure determinations for the R = Et and Y = H, as a dichloromethane solvate [6], and R = iPr with Y = Me [7] and Y = NO2, isolated as a di-chloroform solvate [8], species have been described. In this contribution, the crystal and molecular structures of the R = iPr and Y = Cl compound isolated as an acetonitrile di-solvate, (I), is described.

The molecular structure of the binuclear species in (I) is shown in the figure (70% displacement ellipsoids; unlabelled atoms are related by the symmetry operation (i) 2 − x, −y, 2 − z). The crystallographic asymmetric unit comprises half a binuclear molecule, as the Fe atom is situated on a centre of inversion, and a solvent acetonitrile molecule. The independent gold(I) atom adopts the expected linear geometry [P1—Au—S1 = 173.31(2)°], being coordinated by phosphane-P [Au—P1 = 2.2560(7) Å] and thiolate-S [Au—S1 = 2.3099(7) Å] atoms. The crystal structure of the uncoordinated ligand in its protonated form, i.e. iPrOC(=S)N(H)C6H4Cl-4, is available in the literature [9]. The C1—S1 [1.755(3) Å] and C1—N1 [1.265(3) Å] bond lengths in (I) are significantly elongated and contracted compared with the equivalent bonds, i.e. 1.6708(15) and 1.3388(18) Å, respectively, in the acid. As is uniformly found in dppf{Au[SC(OR)=NC6H4Y-4]}2 structures, an intramolecular Au⋯O interaction is observed. In (I), the Au⋯O separation is 3.026(2) Å.

The molecular packing for (I) features P-phenyl-C—H⋯N(imino) [C23—H23⋯N1ii: H23⋯N1ii = 2.49 Å, C23⋯N1ii = 3.412(4) Å with angle at H23 = 163° for (ii) 2 − x, − y, 1 − z] interactions that lead to the formation of supramolecular chains with a linear topology along the c-axis. The other directional interactions are of the type cyclopentadienyl-C—H⋯π(P-phenyl) [C12—H12⋯Cg(C31–C36)iii: H12⋯Cg(C31–C36)iii = 2.85 Å with angle at H12 = 156° for (iii) 1 − x, −y, 2 − z] and chlorophenyl-C—Cl⋯π(P-phenyl) interactions are noted [C5—Cl1⋯Cg(C21–C26)iv: Cl1⋯Cg(C21–C26)iv = 3.4004(13) Å with angle at Cl1 = 129.10(10)° for (iv) 1 − x, − y, 1 − z] which link chains into a supramolecular layer in the ac-plane. The layers stack along the b-axis without directional interactions between them. The closest contact between the binuclear and solvent acetonitrile molecules is a weak P-phenyl-C—H⋯N(acetonitrile) interaction [C26—H26⋯N41v: H26⋯N41v = 2.70 Å, C26⋯N41v = 3.483(6) Å with angle at H26 = 141° for (v) x, y, 1 + z].

In order to assess the molecular packing further, the Hirshfeld surfaces were calculated along with the full and delineated two-dimensional fingerprint plots employing Crystal Explorer 17 [10] and literature procedures [11]. The most dominant contribution to the calculated surface is from H⋯H contacts at 45.9% with the next most significant contribution coming from H⋯C/C⋯.H contacts, at 23.1%. The percentage contribution from H⋯N/N⋯H contacts is 6.3% with characteristic spikes due to the C—H⋯N interactions being apparent. Other significant contributions are made by H⋯S/S⋯H contacts [7.4%], at distances greater that van der Waals separation as well as contacts involving the chloride atom, i.e. H⋯Cl/Cl⋯H [7.6%] and C⋯Cl/C⋯Cl [3.1%]. The structure of the R = iPr with Y = Me derivative [7], (II), also features P-phenyl-C—H⋯N(imino) interactions leading to supramolecular chains as described for (I). Reflecting the absence of the chloride substituent present in (I), the H⋯H surface contacts in (II) increases to 60.0% followed by H⋯C/C⋯H contacts at 25.0%.

Finally, it is noted that there are no Au⋯Au (aurophilic) interactions in (I), nor are they observed in (II) [7] and in the R = Et and Y = H compound [6]. These three structures have the common feature of having the iron atom located on a centre of inversion. By contrast, the two structures with R = Me and Y = NO2 [5] and R = iPr and Y = NO2 [8] are 2-fold symmetric and feature intramolecular Au⋯Au interactions.
