Crystallographic data on the stable and metastable phases of the high‐temperature forms of the substances of the series of substituted naphthalenes are given. The data are used to calculate for each pair of substances the coefficient ɛ K of molecular homeomorphism as well as the coefficient ɛ m of crystalline isomorphism, which allow a comparison of the (stable and/or metastable) crystal framework.
