This study analyzed the intermolecular interactions in finasteride drug crystals using X-ray and Hirshfeld surface analysis. The study found that the crystals are stabilized mainly by hydrogen bonds and weak interactions, and can be classified as synthon pseudopolymorphs. The study can be useful for crystal engineering of aza steroid drugs.
