2-(Diphenylthiophosphino)dimethylaminomethylferrocene is a key intermediate in the synthesis of various ferrocenyl ligands. During one such synthesis, the title compound, [Fe(C5H5)(C20H22NPS)](C12H10PS2), was isolated as a by-product. It is built up by association of (2-(diphenylphosphino)ferrocenyl)methyl)dimethylammonium cations and diphenylphosphino dithioate anions. N—H⋯S, C—H⋯S and C—H⋯π interactions link the anions and cations. Each anion–cation pair is linked two by two through C—H⋯π interactions, forming pseudo dimers.

In a schlenk tube under argon 4gr of crude (2-diphenylphosphino) dimethylaminomethyl ferrocene (0,47 mmol) were dissolved in 100 ml of dichloromethane, 1,7gr of sulfur (53 mmol) were then added and the solution was heated to reflux for 2 h. The crude product was purified and crystallized at RT. Several days later, orange crystals suitable for X-ray analyses, were obtained.
All H atoms attached to C atoms were fixed geometrically and treated as riding with C—H = 0.98 Å (methyl), 0.99 Å (methylene) and 0.95 Å (aromatic) with Uiso(H) = 1.2Ueq(Cmethylene, Caromatic) and Uiso(H) = 1.5Ueq(Cmethyl). H atom attached to nitrogen was freely refined with Uiso(H) = 1.2Ueq(N).
2-(diphenylthiophosphino)dimethylaminomethylferrocene is a key intermediate in the synthesis of various ferrocenyl ligands (Routaboul et al., 2005; Mateus et al., 2006; Routaboul et al., 2007; Le Roux et al., 2007; Audin et al., 2010;), in our laboratories. The last step of the synthesis of 2-(diphenylthiophosphino)dimethylaminomethylferrocene is a sulfurization of 2-(diphenylphosphino)dimethylaminomethylferrocene without any purification with an excess of elemental sulfur (Mateus et al., 2006). During this synthesis, small amounts of dimethyl-(2-(diphenylthiophosphino)ferrocenyl)methylammonium diphenylphosphinodithioato can be observed in the crude materials. We were able to obtain pure salt fractions by flash
on silicagel. Monocrystals suitable for X-ray could be grown from a dichloromethane solution by slow diffusion of hexane.The π hydrogen interactions. The anion-cation couple are linked two by two through intermolecular C—H···π interactions (Fig. 2; Table 1).
of the title compound contains a (2-(diphenylphosphino)ferrocenyl)methyl)dimethylammonium cation and a diphenylphosphino dithioate anion which are linked through N—H···S hydrogen bond (Fig. 1; Table 1). Besides this rather strong hydrogen bond, there are weaker C—H···S and C—H···In the cation, the two Cp rings have roughly a
with a twist angle of 20.6 (2)° and they are slightly bent with respect to each other making a dihedral angle of 4.72 (12)°. As observed in the related 2-(diphenylthiophosphino)-dimethylaminomethylferrocene (Mateus et al., 2006), the S atom is displaced undo towards the Fe atom by 1.149 (4) Å from the Cp ring. The C2—C21—N1 plane is making a dihedral angle of 58.9 (1)° with the corresponding Cp ring whereas in the above ferrocenylamine (Mateus et al., 2006) the corresponding angle was roughly 90°. The C21—N1 distance of 1.502 (2) Å is similar to the 1.526 (2) Å observed in the reported ferrocenylammonium cation, [FeCp2PPh2(CH2NMe2CH2Ph)]+ (Štěpnička & Císařová, 2003).The geometry of the anion fully agrees with related structures containing the same anion (Alison et al., 1971; Fackler et al., 1982; Silvestru et al., 1995).

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. |

2-(diphenylthiophosphino)dimethylaminomethylferrocene is a key intermediate in the synthesis of various ferrocenyl ligands (Routaboul et al., 2005; Mateus et al., 2006; Routaboul et al., 2007; Le Roux et al., 2007; Audin et al., 2010;), in our laboratories. The last step of the synthesis of 2-(diphenylthiophosphino)dimethylaminomethylferrocene is a sulfurization of 2-(diphenylphosphino)dimethylaminomethylferrocene without any purification with an excess of elemental sulfur (Mateus et al., 2006). During this synthesis, small amounts of dimethyl-(2-(diphenylthiophosphino)ferrocenyl)methylammonium diphenylphosphinodithioato can be observed in the crude materials. We were able to obtain pure salt fractions by flash chromatography on silicagel. Monocrystals suitable for X-ray diffraction analysis could be grown from a dichloromethane solution by slow diffusion of hexane.
The asymmetric unit of the title compound contains a (2-(diphenylphosphino)ferrocenyl)methyl)dimethylammonium cation and a diphenylphosphino dithioate anion which are linked through N—H···S hydrogen bond (Fig. 1; Table 1). Besides this rather strong hydrogen bond, there are weaker C—H···S and C—H···π hydrogen interactions. The anion-cation couple are linked two by two through intermolecular C—H···π interactions (Fig. 2; Table 1).
In the cation, the two Cp rings have roughly a staggered conformation with a twist angle of 20.6 (2)° and they are slightly bent with respect to each other making a dihedral angle of 4.72 (12)°. As observed in the related 2-(diphenylthiophosphino)-dimethylaminomethylferrocene (Mateus et al., 2006), the S atom is displaced undo towards the Fe atom by 1.149 (4) Å from the Cp ring. The C2—C21—N1 plane is making a dihedral angle of 58.9 (1)° with the corresponding Cp ring whereas in the above ferrocenylamine (Mateus et al., 2006) the corresponding angle was roughly 90°. The C21—N1 distance of 1.502 (2) Å is similar to the 1.526 (2) Å observed in the reported ferrocenylammonium cation, [FeCp2PPh2(CH2NMe2CH2Ph)]+ (Štěpnička & Císařová, 2003).
The geometry of the anion fully agrees with related structures containing the same anion (Alison et al., 1971; Fackler et al., 1982; Silvestru et al., 1995).
