The asymmetric unit of the title compound, C47H58N6O6, comprises three independent molecules, in one of which one tert-butyl group is disordered in a 1:1 ratio. The molecule is a di(aryl)methane having two aliphatic and one N-heterocyclic substituent in each aryl ring. For the molecule having the disordered tert-butyl group, the aryl rings make an angle of 115.3 (2)degrees at the methylene carbon; one aryl ring is aligned at 42.0 (1)degrees with respect to the N-heterocyclic substituent and the other at 48.7 (1)degrees with respect to its substituent. The two ordered molecules are disposed about a pseudo center of inversion. The pairs of twist angles in these two molecules differ [52.7 (1) and 61.7 (1)degrees, and 29.1 (1) and 58.5 (1)degrees].
