Research speed reading in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world.. , Safety of N-Cyclohexyltaurine, 103-47-9, Name is N-Cyclohexyltaurine, molecular formula is C8H17NO3S, belongs to thiazines compound. In a document, author is Yennawar, Hemant P., introduce the new discover.
Crystal structure of N-[(2S,5R)-4-oxo-2,3-diphenyl-1,3-thiazinan-5-yl]acetamide 0.375-hydrate
The asymmetric unit of the title compound, C18H18N2O2S.0.375H(2)O, has two independent organic molecules (A and B) and 3/4 of a water molecule distributed over three sites. In molecule A, the 1,3-thiazine ring is in a boat conformation, with the C atoms at the 2- and 5-positions out of the plane. The angle between the two phenyl rings is 51.70 (12)degrees. In molecule B, the thiazine ring is in a half-chair conformation, with the S atom forming the back of the half chair. The angle between the two phenyl rings is 84.44 (14)degrees. The A molecule features an intramolecular N-H center dot center dot center dot O hydrogen bond, which closes an S(5) ring motif. In the crystal, the corresponding N-H grouping of the B molecule participates in an intermolecular hydrogen bond to the A molecule. The A molecule participates in a C-H center dot center dot center dot O interaction back to the B molecule, whilst the B molecule features an intramolecular C-H center dot center dot center dot O link, which generates an S(10) loop.
