(R)-Baclofen [(R)-4-amino-3-(4-chlorophenyl)-butanoic acid].

This article provides the first single-crystal XRD-based structure of enantiopure (R)-baclofen (form C), C10H12ClNO2, without any co-crystallized substances. In the enantiopure title compound, the molecules arrange themselves in an orthorhombic crystal structure (space group P212121). In the crystal, strong hydrogen bonds and C--H...Cl bonds interconnect the zwitterionic molecules. [ABSTRACT FROM AUTHOR]
