Crystal and molecular structure of 1-(4-bromophenyl)azetidin-2-one
Abstract
Crystals of the title compound are monoclinic with a= 10·175, b= 7·403, c= 11·804 Å, β= 99·8° space group P21/a, with Z= 4. The structure was solved by the heavy-atom method and refined by block-diagonal least-squares technique to R 0·058 from diffractometer data consisting of 1814 reflections. Both the β-lactam and the phenyl rings are essentially planar, the torsion angle about the bond joining the two rings being 5·5°.
