2-(2H-Benzotriazol-2-yl)-6-[(diethyl­amino)meth­yl]-4-methyl­phenol

In the title compound, C18H22N4O, the dihedral angle between the planes of the benzotriazol unit and the phenyl ring of the phenoxy group is 6.4 (2)°. There is an intramolecular O—H⋯N hydrogen bond between the phenol and benzotriazol groups.

(E)-N-[2-(Benzyl­iminometh­yl)phen­yl]-2,6-diisopropyl­aniline

The molecular conformation of the title compound, C26H30N2, is reinforced by an intramolecular N—H⋯N hydrogen bond, resulting in an almost planar [mean deviation of 0.023 (2) Å] S(6) ring. The dihedral angles between the central benzene ring and the terminal unsubstituted and substituted aromatic rings are 64.45 (9) and 89.40 (8)°, respectively.

(E)-N-{2-[1-(Benzyl­imino)eth­yl]phen­yl}benzamide

In the title compound, C22H20N2O, the molecular conformation is supported by an intramolecular N—H⋯N hydrogen bond, resulting in an almost planar [mean deviation = 0.048 (2) Å] S(6) ring. The dihedral angles between the central benzene ring and the imine- and amide-substituted aromatic rings are 76.6 (2) and 11.7 (2)°, respectively.

Bis(μ-9-anthracenemethano­lato)bis­[dimethyl­aluminium(III)]

The title complex, [Al2(CH3)4(C15H11O)2], is dimeric bridged through the O atoms of the 9-anthracenemethanolate anions. Each Al atom is tetracoordinated by two bridging O atoms from two different 9-anthracenemethanolate ligands and by two C atoms from two methyl groups, forming a distorted tetrahedral environment. The average Al—O bond distance in the Al2O2 core is 1.845 Å.

2-(2H-Benzotriazol-2-yl)-4-methyl-phenyl diphenyl-phosphinate.

In the title molecule, C25H20N3O2P, the dihedral angle between the mean planes of the benzotriazol ring system and the N-bonded benzene ring is 45.8 (2)°. All but one of the angles at the P atom show slight distortions from an ideal tetrahedral geometry.
