In the title complex, [Mn(C(28)H(18)N(2)O(2))(N(3))(H(2)O)], the Mn(III) ion adopts a distorted fac-MnO(3)N(3) octa-hedral geometry arising from the O,N,N',O'-tetra-dentate Schiff base ligand, an azide ion and a water mol-ecule. In the crystal, inter-molecular O-H⋯(O,O) and O-H⋯N hydrogen bonds and π-π inter-actions [centroid-centroid separation = 3.5535 (13) Å] link the mol-ecules into chains.
