Abstract

In the title compound, C(31)H(39)Br(2)N(3)O(6)S(2), a 17-membered aza-macrocyclic ligand containing two ether O and three aza N atoms, the three pendant aromatic rings form an 'E' shape. The dihedral angles between the central benzene ring and the side ones are 17.8 (3) and 7.4 (3)degrees , and the dihedral angle between the tosyl rings is 10.6 (3)degrees . The methyl group is disordered over two orientations, with occupancies of 0.52 (15) and 0.48 (15).
