Dichloridotriphenylantimony(V)-bis(pyrrolidin-1-ylthiocarbonyl) disulfide (1/1)

L. Quan, H. Yin, J. Zhai and D. Wang

Abstract top

The asymmetric unit of the title compound, [Sb(C6H5)3Cl2]·C10H16N2S4, comprises a bis(pyrrolidinylthiocarbamoyl) molecule and a dichlorotriphenylantimony(V) complex. In the Sb complex, the central atom is coordinated by three C atoms of the three phenyl ligands and two Cl atoms in a slightly distorted trigonal-bipyramidal geometry. The thiocarbamoyl units, connected via the disulfide bond, are approximately perpendicular to each other. The molecules are connected by weak C-H...S and C-H...Cl hydrogen-bonding interactions into two one-dimensional supramolecular chains.

Comment top

In the title complex, the antimony atom is coordinated by three C atoms of three phenyl ligands and two Cl atoms in a slightly distorted trigonal-bipyramidal geometry. Atoms Cl1, Cl2 of the complex lie in axial positions (Fig. 1), with the axial angle Cl1—Sb1—Cl2 178.65 (4)°, deviating substantially from the linear value of 180°. The distances Sb—Cl also vary merely with the role they play in the structure: Sb1—Cl1 = 2.4720 (9) Å and Sb1—Cl2 = 2.4792 (10) Å. In the bis(pyrrolidinylthiocarbamoyl) molecule of the title compound, the thiocarbamoyl moieties, connected via the disulfide bond (S1—S3 = 2.0029 (17) Å), are approximately perpendicular to each other. A Newman projection, calculated with PLATON, with a view along the disulfide bond results in a dihedral angle of 87 ° for C1—S1—S3—C6 (Spek, 2003).

The Dipyrrolidylthiuram disulfide molecule, (which is another name of the organic part in our structure) shows a planar model with crystallographic inversion symmetry in the midpoint of the S—S bond (Williams et al., 1983).

In the similar structure bis(N,N-dicyclohexylthiocarbamoyl) disulfide, a crystallographic twofold axis passes through the midpoint of the S—S bond (Li et al., 2006). The disulfide S—S distance is close to the distances observed in free (uncoordinated) disulfides (Kumar et al., 1990).

The S atoms of bis(pyrrolidinylthiocarbamoyl) and the Cl atoms of dichlorotriphenylantimony play a significant role in the crystal packing, linking the complex molecules by weak C—H···S and C—H···Cl (Table 1) hydrogen bonds to form two one-dimensional supramolecular chains (Fig. 2).

Experimental top

Chlorotriphenylantimony (0.2 mmol) was dissolved in benzene (15 ml) and bis(pyrrolidinylthiocarbamoyl) (0.2 mmol) dissolved in methanol was added with stirring at room temperature for eight hours and then filtered. Orange crystals suitable for X-ray analysis were obtained by slow evaporation of a petroleum/dichloromethane (1:2 v/v) solution over a period of twenty days (yield 85%. m.p. 432k). Anal. Calcd (%) for C28H31N2S4Cl2Sb(Mr = 716.48): C, 46.94; H, 4.36; N, 3.91. Found (%): C, 46.89; H, 4.31; N, 3.87.

Refinement top

The H atoms bound to C of pyrrolidine were located in a difference map and were refined as riding on their respective C atoms with distances C—H = 0.97 Å and with Uiso(H) = 1.2Ueq(C). The other H atoms were constraint at calculated positions (riding mode), with C—H = 0.93 Å and Uiso(H) = 1.2 Ueq(C).
