چکیده
The title compound, C28H40N2, was obtained from the condensation reaction of 4-tert-butyl-2,6-di-methyl-aniline and butane-2,3-dione. The mol-ecule lies on an inversion centre. The C=N bond has an E conformation. The plane of the benzene ring is almost perpendicular to the 1,4-di-aza-butadiene mean plane [dihedral angle = 89.8 (9)°].

The whole molecule of the title compound, C22H28N2, (I), is generated by inversion symmetry. The mol-ecule is rather similar to that of 2,3-bis-[(2-tert-butyl-phen-yl)imino]-butane, (II), a di-imine ligand comprising similar structural features [Ferreira et al. (2006 ▶). Acta Cryst. E62, o4282-o4284]. Both ligands crystallize with the -N=C(R)-C(R)=N- group around an inversion centre, in a trans...

In the title solvated salt, C9H14N(+)·Cl(-)·C19H24O2·0.5C7H7, two mol-ecules of 4,4'-(propane-2,2-di-yl)bis-(2,6-di-methyl-phenol) are linked via O-H⋯Cl hydrogen bonds to two chloride ions, each of which is also engaged in N-H⋯Cl hydrogen bonding to a 4-tert-butyl-pyridinium cation, giving a cyclic hydrogen-bonded entity centred at 1/2, 1/2, 1/2. The toluene solvent mol-ecule resides in the lat...

In the title compound, C(11)H(21)NO(5), the H atoms of the hydr-oxy groups are disordered over two positions, each in a 1:1 ratio. In the crystal, inter-molecular O-H⋯O hydrogen bonds link pairs of mol-ecules into centrosymmetric dimers. Weak inter-molecular O-H⋯O inter-actions further link these dimers into chains extended in the [100] direction.
