“…The angle between the planes of the amide group and phenyl group A is -29.1 °. This is significantly different from the twist angle, 24.6 ° , found in benzamide (Blake & Small, 1972). The angle between the planes of the amide group and phenyl ring B is 35.9 ° , which is significantly different from the corresponding value, 17.6 ° , found in acetanilide (Brown, 1966).…”
Abstract. C20N202H16, monoclinic, P2~/c, a = 18.065(1), b = 5.247(1), c = 8.027(1) A, fl = 93.99 (1) °, Z = 2. The crystal structure has been refined by least-squares techniques. R w = 7.3%. The structure contains planar phenyl rings which are rotated with respect to the plane of the amide group owing to steric hindrance. The molecules are connected in one dimension by means of hydrogen bonds.

“…The crystal structure of benzamide was determined by single-crystal X-ray analysis at room temperature by Blake & Small (1972). We report a neutron diffraction refinement at 15 and 123K to provide more precise molecular dimensions and for later use * Present address: Biology Department, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
