Abstract: The title compound, C 12 H 20 O 6 , crystallizes in the tetragonal space group P 4, with two crystallographically independent molecules in the asymmetric unit. Each independent molecule contains one hydroxy group that acts as both a hydrogen-bond donor and an acceptor. In the crystal, separate O—H...O hydrogen-bonding interactions connect four symmetry-related molecules into cyclic tetrameric assemblies around the crystallographic fourfold axes. The corresponding D-enantiomer has previously been determined at room temperature [CSD refcode FOYTAO; Lis & Weichsel (1987). Acta Cryst. C 43 , 1954–1956] and redetermined at 173 K [Yathirajan et al. (2004). CSD Communication (FOYTAO01). CCDC, Cambridge, England]. The close agreement in space group, asymmetric-unit contents and crystal packing indicates that the present L-enantiomer is isostructural with the previously reported D-enantiomer.
