2,2'-[1,5-Bis(4-amino-phen-yl)-1,5-dihydro-benzo[1,2-d;4,5-d']diimidazole-2,6-di-yl]diphenol.

ABSTRACT: The title mol-ecule, C(32)H(24)N(6)O(2), has a crystallographic inversion centre in the middle of the benzodiimidazole core. It exists as the enol-imine tautomeric form and exhibits a strong intra-molecular O-H⋯N hydrogen bond. The dihedral angles between the planes of the 2-hy-droxy-phenyl and 4-amino-phenyl substituents and the plane of the benzodiimidazole unit [12.69 (8) and 84.71 (8)°, respectively] differ significantly due to steric reasons. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming a two-dimensional network.
