4-Bromo-N,N'-bis­(4-methoxy­phen­yl)benzamidine

The title compound, C21H19BrN2O2, is an amidine containing electron-donating methoxy groups and a bulky Br atom on the benzene rings. The solid-state structure reveals a non-centrosymmetric molecule, with an E configuration around the C=N double bond. The C—N bonds show distinct amine [1.3689 (19) Å] and imine [1.285 (2) Å] characteristics. In the crystal, symmetry-related molecules are linked via a very weak N—H⋯N interaction, and C—H⋯O and C—H⋯π interactions.
