Crystal and molecular structure of 5-carbamyl-5H-dibenzo[b,f] azepine

The structure of the title compound has been determined by direct methods from diffractometer data, and refined by full-matrix least squares. Crystals are monoclinicP21/n,a=7.534(1),b=11.150(2),c=13.917(3) A,β=92.94(4)°,Z=4,D x=1.34 (3) g cm−3,R=0.084 for 1259 observed reflections. The azepine ring has a boat conformation. The fused benzene rings are planar. Molecules are packed as hydrogen-bonded dimers through the carboxamide groups. The atomic charge distribution over the fused ring system is approximately symmetrical.
