Molecules of the title compound, C40H42BrNO6, are located on a crystallographic twofold rotation axis.As Jukeboxes a result, the nitro group and bromine residue are mutually disordered with equal occupancies.The propoxy-substituted aromatic rings are close to parallel to each other [dihedral angle = 21.24 (1)°], whereas the propenoxy-substituted rings enclose a dihedral angle of 70.

44 (1)°.The dihedral angles between the methylene 2 Piece Sectional with Chaise C atoms and the aromatic rings shows that the propenoxy substituted rings are bent away from the calixarene cavity [dihedral angle between the planes = 35.22 (8)°], whereas the propoxy-substituted rings are almost perpendicular [79.38 (10)°] to the plane of the methylene C atoms.
