3-(4-Methylphenyl)-1-phenyl-3-(4,5,6,7-tetrahydro-1,2,3-benzoselenadiazol-4-yl)propan-1-one

In the title compound, C22H22N2OSe, the fused six-membered ring of the 4,5,6,7-tetrahydrobenzo[d][1,2,3] selenadiazole group adopts a near to envelope (E form) conformation and the five-membered 1,2,3-selenadiazole ring is essentially planar (r.m.s. deviation = 0.0059 Å). In the crystal, adjacent molecules are interlinked through weak intermolecular C—H⋯π interactions.
