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⋯O inter-molecular hydrogen bonds and one weak C - H⋯π inter-action. C - H⋯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⋯C(PhOMe) line] of 6.94 (2)° shows the degree of planarity of the acridinedione system. The dihedral angle between the planes of the two aromatic rings is 9.66 (2)°. © 2007 International Union of Crystallography. All rights reserved.
