Crystal structure of (2R)-1-(methylsulfonyl)oxypropan-2-aminium chloride:a chiral molecular salt

摘要

In the title chiral molecular salt, C4H12NO3S+.Cl-, the cation is protonated at the N atom, producing [RNH3]+, where R is CH3SO2OCH2C(H)CH3. The N atom in the cation is sp3-hybridized. In the crystal, cations and anions are connected by strong N-H...Cl hydrogen bonds to generate edge-shared 12-membered rings of the form {...Cl...HNH}3. This pattern of hydrogen bonding gives rise to zigzag supramolecular layers in the ab plane. The layers are connected into a three-dimensional architecture by C-H...O hydrogen bonds. The structure was refined as an inversion twin.
