The title compound [systematic name: 2-oxo- ,2-diphenyl- -(propan-2-yl)acetamide], C H NO , was synthesized and its photoreactive properties in the crystalline state were investigated. In the mol-ecule, the carbonyl group attached to the phenyl ring adopts an - configuration with respect to the isopropyl group. Moreover, the distance between the C atom of the carbonyl group and the N-bound C atom of the isopropyl group is 3.845 (2) Å, which is much longer than 3.2 Å, the threshold for photoreactions to take place in the mol-ecule. As a result, the crystal did not photoreact upon UV light irradiation. In the crystal, the mol-ecules are linked weak inter-molecular C-H⋯O hydrogen bonds, forming a layer structure parallel to the plane.
