Crystal structure of racemic 2-[(ß-arabinopyranosyl)sulfanyl]-4,6-diphenylpyridine-3-carbonitrile

Hammad, Sherif. F.; Masoud, Doaa M.; Elgemeie, Galal H.; Jones, Peter G. GND

In the racemic title compound, C23H20N2O4S, the sulfur atom is attached equatorially to the sugar ring with unequal S—C bonds, viz.: S—Cs = 1.808 (2) and S—Cp = 1.770 (2) Å (s = sugar, p = pyrid­yl). The dihedral angles between the pyridine ring and its attached phenyl groups are 42.24 (8) and 6.37 (14)°. In the crystal, a system of classical O—H⋯O and O—H⋯(O,O) hydrogen bonds links the mol­ecules to form tube-like assemblies propagating parallel to the c-axis direction. Weak C—H⋯N inter­actions are also observed.
