(3R*,4R*)-3-Isopropyl-4-phenylazetidin-2-one at 150 K

Abstract

The title compound, C12H15NO, crystallized in the centrosymmetric space group C2/c with one mol­ecule as the asymmetric unit. There is a single conventional N—H⋯O hydrogen bond, with a donor–acceptor distance of 2.912 (1) Å, which forms an R{_2^2}(8) cyclic dimer about a center of symmetry. There is a single significant intermolecular C—H⋯O interaction, which also forms an R{_2^2}(8) cyclic dimer about a center of symmetry. Taken together, these interactions form chains propagating along [110]. Structural comparisons are made with another β-­lactam, (1′R*,3R*,4S*)-3-(1′-hydroxy­ethyl)-4-phenylazet­id­in-2-one.
