10-(4-bromophenyl)-9-(4-methoxyphenyl)-3,3,6,6-tetramethyl-3,4,6,7-tetrahydro-acridine-1,8(2H, 5H, 9H, 10H)-dione

Abstract

The crystal structure of the title compound, C30H32BrNO3, is stabilized by two C-H center dot center dot center dot O intermolecular hydrogen bonds and one weak C-H center dot center dot center dot pi interaction. C-H center dot center dot center dot O hydrogen bonds generate C(10) chains and an R-2(2)(16) ring motif. In the title compound, the central pyridine ring in the acridinedione system is approximately planar while the outer two rings adopt half-chair conformations. The buckling angle between the two halves [at the N center dot center dot center dot C(PhOMe) line] of 6.94 (2)degrees shows the degree of planarity of the acridinedione system. The dihedral angle between the planes of the two aromatic rings is 9.66 (2)degrees.
