In the title compound, C3H8O4S2, the two central S—C(H2) bond lengths are almost identical [1.781 (2) and 1.789 (2) Å]. In the crystal, each molecule utilizes CH2 and CH3 bonds to form weak C—HO hydrogen bonds to six other molecules, thus linking molecules into a three-dimensional network.

The title compound, C18H28N2S2·CHCl3, crystallizes as a zwitterion. The C—S bonds are almost equivalent, with lengths of 1.666 (3) and 1.657 (3) Å. The S—C—S bond angle is expanded to 129.54 (16)° and the N—C—N angle is reduced to the tetrahedal value of 108.8 (2)°. In the crystal, adjacent molecules are linked via C—HS hydrogen bonds, forming chains along [100]. The chloroform solvent molecule, which is disordered over two positions [occupancy ratio = 0.51 (2):0.49 (2)], is linked to the chain by bifurcated C—H(S,S) hydrogen bonds.
