3-(4-Bromophenyl)cyclopent-2-en-1-one
In the title compound, C11H9BrO, the cyclopentenone ring is almost planar with an r.m.s. deviation of 0.0097 Å. The largest inter-ring torsion angles [2.4 (3), 1.3 (3) and 3.53 (2)°] reveal only a very small twist between the rings, and suggest that the two rings are conjugated. The molecule is slig...
