We prepared cocrystals of DL-2-Hydroxy-2-phenylacetic acid (D, L-H2ma) with the pyridinecarboxamide isomers, picolinamide (pic) and isonicotinamide (inam). They were characterized by elemental analysis, single crystal powder X-ray, IR spectroscopy 1H 13C NMR. The molecular structures (pic)-(D-H2ma) (1), (nam)-(L-H2ma) (2) (inam)-(L-H2ma) (3) studied. packing is stabilized primarily hydrogen bon...
