Crystalline Vorinostat potassium salt form A characterized by a powder XRD pattern having peaks at about 4.9 and 7.4 ± 0.2 degrees 2-theta and any 3 peaks selected from the lis consisting of: 12.3, 19.8, 20.9, 22.1, 22.8, 28.7 and 29.5 ± 0.2 degrees 2-theta is provided. Crystalline Vorinostat potassium salt form A may be polymorphically pure. Processes for preparing crystalline Vorinostat potassium salt form A are also provided. Further provided i crystalline Vorinostat form VI characterized by a powder XRD pattern having peaks at about 14.3, 14.8, 17.6, 21.4 and 23.1 ± 0.2 degrees 2-theta as well as processes for preparing crystalline Vorinostat form VI.
