چکیده
The asymmetric unit of the title compound, C(47)H(58)N(6)O(6), comprises three independent mol-ecules, in one of which one tert-butyl group is disordered in a 1:1 ratio. The mol-ecule is a di(ar-yl)methane having two aliphatic and one N-heterocyclic substituent in each aryl ring. For the mol-ecule having the disordered tert-butyl group, the aryl rings make an angle of 115.3 (2)° at the methyl-ene carbon; one aryl ring is aligned at 42.0 (1)° with respect to the N-heterocyclic substituent and the other at 48.7 (1)° with respect to its substituent. The two ordered mol-ecules are disposed about a pseudo center of inversion. The pairs of twist angles in these two mol-ecules differ [52.7 (1) and 61.7 (1)°, and 29.1 (1) and 58.5 (1)°].
