2,2'-Diamino-4,4'-bi-1,3-thiazolium (2R,3R)-tartrate

B.-X. Liu and D.-J. Xu

Abstract: Crystals of the title chiral compound, C₆H₈N₄S₂²⁺·C₄H₄O₆^2-, were obtained from a solution containing diaminobithiazole (DABT) and racemic tartaric acid. The crystal structure consists of a protonated DABT dications (H₂DABT) and (2R,3R)-tartrate dianions linked via hydrogen bonding. An overlapped arrangement and a centroid-to-centroid separation of 3.4620  (11)  Å between nearly parallel thiazole rings of adjacent H₂DABT cations indicate the existence of - stacking in the crystal structure.
