Abstract

In the title compound {systematic name: 4-[2,3-dibromo-3-(4-bromo­phen­yl)propano­yl]-3-(4-meth­oxy­phen­yl)-1,2,3-oxa­dia­zol-3-ylium-5-olate}, C18H13Br3N2O4, the central oxadiazole ring, which is essentially planar with a maximum deviation of 0.016 (3) Å, makes dihedral angles of 29.98 (16) and 52.04 (16)°, respectively, with the terminal bromo-substituted and meth­oxy-substituted benzene rings. An intra­molecular C—H⋯O hydrogen bond generates an S(6) ring motif.
