Abstract

The title compound, C12H20O6, crystallizes in the tetra-gonal space group P4, with two crystallographically independent mol-ecules in the asymmetric unit. Each independent mol-ecule contains one hy-droxy group that acts as both a hydrogen-bond donor and an acceptor. In the crystal, separate O-H⋯O hydrogen-bonding inter-actions connect four symmetry-related mol-ecules into cyclic tetra-meric assemblies around the crystallographic fourfold axes. The corresponding d-enanti-omer has previously been determined at room temperature [CSD refcode FOYTAO; Lis & Weichsel (1987 ▸). Acta Cryst. C43, 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-enanti-omer is isostructural with the previously reported d-enanti-omer.
