The mol­ecular structure of the title compound, C9H14O4S3, exhibits intra­molecular C—H⋯S hydrogen bonds. In the crystal, pairs of O—H⋯O hydrogen bonds lead to the formation of centrosymmetric dimers, which are in turn connected by weak C—H⋯O inter­actions. The combination of these inter­actions generates edge-fused R22(8) and R22(20) rings running along [211].

Comment top

The title compound, C9H14O4S3, belongs to a series of organic trithiocarbonates that have received special attention due to their applications as pharmaceuticals (Dehmel et al., 2007) or as intermediates in organic synthesis (Metzner et al., 1996). Trithiocarbonates can be used to control the behavior of polymerization reactions (Harrisson & Wooley, 2005; Bilalis et al., 2006; Millard et al., 2006) or they are also used in radical polymerization with RAFT (reversible addition-fragmentation chain transfer) reactions (Moad et al., 2005). A perspective view of the title compound (I), showing the atomic numbering scheme, is given in Fig. 1. The central trithio moiety in (I) is close to symmetric behavior. This behavior is different in an analogous structure (El-khateeb & Roller, 2007), where C1—S2 and C1—S3 bond lengths take values of 1.7733 (16) and 1.7232 (16) Å, respectively. This difference in the bond lengths is probably linked to the different ligand groups to which the trithio central group is connected. The title system shows intramolecular C—H···S interactions. The molecules of (I) are linked by O—H···O hydrogen bonds in their carboxyl terminals, forming centrosymmetric dimers. The O1 and O3 atoms at (x,y,z) act as hydrogen bond donors to O4 and O2 atoms of the carboxyl groups at (-x,-y + 1,-z). These dimers are connected to each other, through the weak C6—H6···O4, allowing them to grow along [211] (see Table 1, Nardelli, 1995). The C6 atom at (x,y,z) acts as hydrogen bond donor to O4 of the carboxy group at (x + 1,-y + 3/2,+z + 1/2). These intermolecular contacts are explained in terms of the substructure shown in Fig. 2. The combination of these interactions generate edge-fused R22(8) and R22(20) rings (Etter, 1990).

Experimental top

The compound (I) was synthesized according to a procedure reported in the literature (Lai et al., 2002). Carbon disulfide (27.4 g, 0.361 mol), chloroform (107.5 g, 0.904 mol), acetone (52.3 g, 0.934 mol), and tetrabutylammonium hydrogen sulfate (2.41 g, 7.11 mmol) were mixed with 120 ml of mineral spirits in a 1 L round bottom flask under nitrogen. Sodium hydroxide (50%) was added dropwise over 90 min to maintain the temperature below 25°. The reaction was stirred overnight. 900 ml of water was added followed by 120 ml of concentrated HCl to acidify the aqueous layer. The mixture was filtered and rinsed with water. It was obtained a yellow cristalline solid which was purified with acetone.

Refinement top

All H-atoms were placed in calculated positions [O—H = 0.82 Å and C—H = 0.96 Å for methyl group] and refined using a riding model approximation with Uiso(H) constrained to 1.5 (O—H and methyl) times Ueq of the respective parent atom.

Special details top

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.
