title: 4-Bromo-N,N'-bis-(4-methoxy-phen-yl)benzamidine.
abstract: The title compound, C(21)H(19)BrN(2)O(2), is an amidine containing electron-donating meth-oxy groups and a bulky Br atom on the benzene rings. The solid-state structure reveals a non-centrosymmetric mol-ecule, 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 mol-ecules are linked via a very weak N-H⋯N inter-action, and C-H⋯O and C-H⋯π inter-actions.
