Abstract: ( $\pm$ )-Tartaric acid, C₄H₆O₆, crystallized from ethanol in space group P $\overline 1$ . The structure is characterized by five hydrogen bonds, including the formation of a centrosymmetric carboxylic acid dimer which forms infinite chains along the body diagonal. These chains form sheets via hydrogen bonding between [alpha] -hydroxyl groups. The sheets are connected through a bifurcated hydrogen bond. Structural comparisons are made with homochiral (2R,3R)-(+)-tartaric acid.

Formula: C₄H₆O₆
