2,7-Bis(2,6-diisopropyl-phen-yl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetra-one.

ABSTRACT

In the title compound, C(38)H(38)N(2)O(4), the 16 atoms comprising the four six-membered rings that are fused together are approximately coplanar (maximum r.m.s. deviation = 0.033 Å). The benzene rings at either ends are nearly perpendicular to the mean plane of the fused-ring system; one is aligned at 80.4 (1) ° and the other at 82.2 (1)°.
