7,8-Dimethyl-11H-indeno[1,2-b]quinoxalin-11-one

Abstract

In the title compound, C17H12N2O, the mean planes of the indene ring and quinoxaline system (r.m.s. deviations = 0.0131 and 0.0082 Å) are approximately parallel to one another, making a dihedral angle of 1.2 (5)°. This means that the indeno[1,2-b]quinoxaline ring is almost in the same plane (r.m.s. deviation = 0.0181 Å).
