Effect of Molecular Perturbation on Polymorphism: The Case of 8-Halotheophyllines (8-Cl-Tph and 8-Br-Tph)

Crystals
The common alkaloid theophylline (Tph) is known to exist in five polymorphic forms. The structures of its 8-halo analogues were previously unreported. Here, we report three polymorphs for 8-chlorotheophylline (8-Cl-Tph) and an additional distinct one for
