Crystal structure of corynoline p-bromobenzoate

Abstract

Crystals of the title compound (3) are monoclinic, space group P2₁/c with Z= 4 in a unit cell of dimensions: a= 12·598(88), b= 14·868(67), c= 13·592(79)Å, β= 115·30(43)°. The structure was solved from diffractometer data by the heavy-atom method and refined by least-squares methods, to R 0·165 for 2008 observed reflexions. The B/C ring junction is cis-fused and rings B and C take the half-chair and the twist-half-boat conformations, respectively.
