N,N′-Bis[3,5-bis(2,6-diisopropylphenyl)phenyl]butane-2,3-diimine

Abstract

The title mol­ecule, C64H80N2, lies on an inversion center wherein the central butane­diimine 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 mol­ecule, 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)°.

N,N′-[(2E,3E)-Butane-2,3-diylidene]bis[4-fluoro-2-(1-phenylethyl)aniline]

“…The dihedral angles between the benzene ring C8-C13 and benzene ring C1-C6 is 84.27 (5)°. The molecular dimensions in the title compound agree very well with the corresponding one reported in a few closely related compounds (Zou et al, 2008;Lohr et al 2011).…”
