Abstract

The title compound, C(32)H(40)N(2)O(4), is a 1,10-diaza-18-crown-6 cryptand with an o-terphenyl bridge. In the polyether ring, two adjacent -CH(2)- groups are disordered with very nearly equal populations of two conformers. The ordered bond lengths are normal, with average C-C = 1.511 (3) Å, C-O = 1.421 (3) Å, and C-N = 1.466 (4) Å. The r.m.s. deviations of the three rings of the terphenyl bridge vary from 0.007 to 0.009 Å and the two rings ortho to one another are twisted by 50.75 (5) and 47.76 (4)° with respect to the third ring. The N⋯N distance is 5.408 (1) Å.
