title: Polymorphism of (Z)-4-bromo-N-(pent-2-enyl)-N-(3-phenylprop-2-ynyl)benzenesulfonamide.
abstract: The title compound, C20H20BrNO2S, has two polymorphic crystal structures with very similar lattice constants. A number of crystals are composites of the two polymorphs. Both crystal structures contain identical layers of molecules. The packing of the layers, however, is different for the two polymorphs.
