3,5,3 ',5 '-Tetramethyl-N,N '-bis(salicylidene)-biphenyl-4,4 '-diamine

Abstract

In the molecule of the title Schiff base compound, C30H28N2O2, the dihedral angles between the phenol rings and the adjacent dimethylbenzene rings [ 60.14 ( 11) and 77.57 ( 11)degrees] are distinctly larger than that formed by the dimethylbenzene rings [ 39.65 ( 11)degrees], possibly as a result of the steric hindrance of the methyl groups and the presence of intramolecular O - H (...) N hydrogen bonds.
