Following Paul Heinrich von Groth's definition, morphotropism, or morphotropy, is the change of a crystal structure produced by isomorphic substitutions. The special case in which these substitutions do not modify the crystal structure is called isomorphotropism. The latter is today more commonly known as isomorphism.
IUPAC defines a morphotropic transition as 'an abrupt change in the structure of a solid solution with variation in composition'.
