Abstract

Twenty-four polymorphic compounds which show between two and four modifications are cited. The compounds described in detail are tetrabutylammonium iodide, tetraheptylammonium bromide, tetraoctylammonium bromide, 3-(3,4,5-trimethoxyphenyl)-2-propenoic acid andl-tyrosine ethyl ester hydrochloride. For the remaining nineteen compounds, only the number of modifications found, and their melting points where possible, are given.
