Source of material

A solution of triethylphosphine solution (Sigma Aldrich; 1.0 M in THF, 1 mL, 1.0 mmol) was added to silver nitrate (Sigma Aldrich; 0.169 g, 1.0 mmol) in acetonitrile (10 mL), followed by the addition of ammonium pyrrolidinedithiocarbamate (Fluka; 0.164 g, 1.0 mmol) in acetonitrile (10 mL). The resulting mixture was stirred for 4 h and left for slow evaporation at room temperature, giving yellow crystals after 4 weeks. Yield: 0.197 g (53%). M. pt (Biobase automatic melting point apparatus MP450): 370 K. IR (Bruker Vertex 70v FTIR Spectrophotometer; cm−1): 1408 (s) ν(C=N), 985 (s) ν(C–S).

Experimental details

The H-atoms were placed in calculated positions (C—H = 0.98–0.99 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2–1.5Ueq(C). The C31a-ethyl group was found to be disordered over two positions. Each component was refined independently with the major component having a site occupancy factor = 0.797(9).

Comment

In connection with recent anti-bacterial screening and pharmacokinetic studies of binuclear phosphanesilver(I) dithiocarbamates, {Cy3PAg(S2CNRR′)}2, complementary crystallographic studies revealed a novel conformation for one of the derivatives [5]. The common feature of the solid-state structures are μ2-bridging dithiocarbamate ligands and a central Ag2S2 core, with the distinction arising in terms of the relative disposition of the dithiocarbamate ligands. In three of the structures, i.e. with R = R′ = Et and CH2CH2OH, and R = Me, R′ = CH2CH2OH, the dithiocarbamate ligands lie to either side of the core, i.e. adopt an anti-conformation. The unusual structure was observed when NRR′ = N(CH2)4, which has a syn conformation as the dithiocarbamate ligands are orientated to the same side of the Ag2S2 core. The majority of related structures adopt the anti-conformation [6], [7], [8], [9], [10], [11], with the only other exceptional structure being that of {Ph2(Me)PAg(S2CNEt2)}n, which, although having a similar mode of coordination of the dithiocarbamate ligand, is a one-dimensional coordination polymer in the solid-state [9]. In continuation of studies in this area, herein, the results of the crystal structure determination of {Et3PAg[S2CN(CH2)4]}2, (I), are described.

The molecular structures of the two independent binuclear molecules of (I) are shown in the figure (70% displacement ellipsoids; the unlabelled atoms in the upper and lower images are generated by the application of the symmetry operations (i) −x, 1 − y, −z and (ii) 1 − x, −y, 1 − z, respectively). As each binuclear complex is disposed about a centre of inversion, the asymmetric unit comprises two half complexes. The dithiocarbamate ligand is tridentate, simultaneously chelating the Ag1 atom [Ag1—S1 = 2.7882(5) Å and Ag1—S2 = 2.5683(5) Å] and bridging the Ag1i atom [Ag1i—S1 = 2.6684(5) Å]; the fourth position in the PS3 coordination geometry is occupied by the phosphane-P1 atom [Ag1—P1 = 2.4017(5) Å]. The Ag1a atom exhibits the same general features but, in this case, the shortest Ag—S bond involves the S1aii atom which links the monomeric units into the dimer [Ag1a—S1a, S2a, S1aii & P1 = 2.7097(5), 2.6278(5), 2.5890(5) & 2.3825(5) Å, respectively]. The four-coordinate geometry defined by the PS3 donor set is highly distorted as seen in the range of angles subtended at the Ag1 atom, i.e. 67.791(15)°, for the S1—Ag1—S2 chelate angle, to 139.496(19)° for S2–Ag1—P1. The range is reduced for the Ag1a atom, i.e. 68.334(15) Å for S1a—Ag1a—S2a to 125.188(19)° for S1aii—Ag1a—P1a. An intramolecular Ag1⋯Ag1i [3.1876(3) Å] contact is noted but, the equivalent separation for the Ag1a-complex is considerably longer at 3.4451(4) Å. This represents the greatest difference between the independent complexes.

In the crystal, weak P-methylene-C—H⋯S(bridging) interactions [C21—H21b⋯S1a: H21b⋯S1a = 2.86 Å, C21⋯S1a = 3.649(3) Å with angle at H21b = 137° and C21a—H21c⋯S1iii: H21c⋯S1iii = 2.78 Å, C21a⋯S1iii = 3.738(3) Å with angle at H21c = 163° for (iii) −x, 1 − y, 1 − z]. As these occur between the independent molecules comprising the asymmetric unit and each of these forms two donor and two acceptor interactions that extend laterally, the complexes are assembled into a two-dimensional array parallel to (1 1 0). The layers stack without directional interactions between them.

Using Crystal Explorer 17 [12] and following standard protocols [13], the Hirshfeld surfaces and two-dimensional fingerprint plots were calculated for each of the independent complexes. There are two dominant surface contacts for the Ag1-complex, namely H⋯H and H⋯S/S⋯H contributing 77.8 and 18.5%, respectively, the latter, in part, reflecting the H⋯S contacts discussed above. A similar dominance is observed for the Ag1a-complex (major component; no significant difference was noted for the minor component), but, with distinct percentage contributions to the Hirshfeld surface, i.e. 80.7 and 17.2%.
