Our work exploring the synthesis and optimization of increasingly hindered thiols led to the synthesis and crystal structure determination of the title compound, C5H8N2OS, a dimethly-substituted 4-thiazolidinone. The molecular packing exhibits a herringbone pattern with the zigzag running along the b-axis direction; the compound crystallizes as chains of hydrogen-bonded dimers formed by N—H...N hydrogen bonds, which build centrosymmetric R 2 2(8) ring motifs in the crystal.

Relative Stereochemistry

The crystal structure determination of the title compound, C13H15IO4, has allowed the relative stereochemistry between the tetrasubstituted C atoms on the tetrahydrofuran moiety to be confirmed. The title compound is a precursor of the ionophoric antibiotic Aplasmomycin. The compound is involved in both intra- and intermolecular hydrogen bonding, the latter link the molecules into chains running along thebaxis.

Lithium Derivative

The title compound, C14H19NO5S, was prepared by nucleophilic addition of the lithium derivative of methylphenylsulfone to (3S,4R)-3,4-isopropylidenedioxypyrroline 1-oxide. There are four molecules in the asymmetric unit. The crystal structure determination confirms the configuration of the chiral centres as 2R,3S,4R. In the crystal, pairs of O—H...N hydrogen bonds link the molecules into dimers.

A Chain

The crystal structure determination of the title compound, C12H10O, has been reported previously [Gupta & Gupta (1975). Acta Cryst. B31, 7–9], with an R value of 0.078. The results reported here are in agreement with the literature data but a more precise molecular geometry is obtained (σ on C—C = 0.002 Å). Intermolecular O—H...O hydrogen bonds connect molecules into a chain running parallel to the [010] direction. This chain is reinforced by two C—H...π interactions.

Supramolecular Chains

In the title compound, C18H19BrFN3S, the 1,2,4-triazole ring is nearly planar with a maximum deviation of −0.009 (3) and 0.009 (4) Å, respectively, for the S-bound C atom and the N atom bonded to the bromofluorophenyl ring. The phenyl and triazole rings are almost perpendicular to each other, forming a dihedral angle of 89.5 (2)°. In the crystal, the molecules are linked by weak C—H...π(phenyl) interactions, forming supramolecular chains extending along the c-axis direction. The crystal packing is further consolidated by intermolecular N—H...S hydrogen bonds and by weak C—H...S interactions, yielding double chains propagating along the a-axis direction. The crystal studied was refined as a racemic twin.
