Crystal structure of (-)-(2R,3S,4R,5R)-5-(1,3-di-thian-2-yl)-3-methyl-1-(triiso-propyl-sil-yloxy)hexane-2,4-diol.
The title compound, C20H42O3S2Si, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. They consist of syn,anti,anti-stereo-tetrads with a 1,3-di-thiane motif and a primary alcohol protected as the triisopropyl silyl ether. The 1,3-di-thiane ring adopts a chair conformation, while the rest of each mol-ecule displays a common zigzag conformation. There is an intra-molecular O-H⋯O hydrogen bond in each mol-ecule. In the crystal, the A and B mol-ecules are linked via O-H⋯O hydrogen bonds, forming -A-B-A--B-- chains along [010]. The absolute structure was determined by resonant scattering (anomalous scattering) [Flack parameter = 0.035 (8)].
期刊介绍：
Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
