title: N,N'-Bis[3,5-bis-(2,6-diisopropyl-phen-yl)phen-yl]butane-2,3-diimine.
abstract: The title mol-ecule, C(64)H(80)N(2), lies on an inversion center wherein the central butane-diimine fragment [N=C(Me)-C(Me)=N] is essentially planar [maximum deviation = 0.002 (2) Å] and its mean plane forms a dihedral of 70.88 (10)° with the attached benzene ring. In the symmetry-unique part of the mol-ecule, the dihedral angles between the benzene ring bonded to the N atom and the other two benzene rings are 89.61 (6) and 82.77 (6)°.
