6,6'-Di-tert-butyl-2,2'-[1,2-phenyl-ene-bis(nitrilo-methyl-idyne)]diphenol.


ABSTRACT: The mol-ecule of the title Schiff base compound, C(28)H(32)N(2)O(2), has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12?(14) and 26.01?(14)°. Four intra-molecular C-H?O hydrogen bonds and two intra-molecular O-H?N hydrogen bonds stabilize the mol-ecular structure. In the crystal packing, mol-ecules are stacked along the a axis and stabilized by ?-? inter-actions [centroid-centroid distance = 3.6724?(17)?Å]. The crystal studied was found to be a non-merohedral twin, the refined ratio of twin components being 0.374?(5):0.626?(5).

The mol-ecule of the title Schiff base compound, C(28)H(32)N(2)O(2), has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12 (14) and 26.01 (14)°. Four intra-molecular C-H⋯O hydrogen bonds and two intra-molecular O-H⋯N hydrogen bonds stabilize the mol-ecular structure. In the crystal packing, mol-ecules are stacked along the a axis and stabilized by π-π inter-actions [centroid-centroid distance = 3.6724 (17) Å]. The crystal studied  ...[more]
