Coefficients of molecular homeomorphism and crystalline isomorphism in the series of 2-R-naphthalene (R = H, F, Cl, CH₃, SH, Br)

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 [epsilon]_K of molecular homeomorphism as well as the coefficient [epsilon]_m of crystalline isomorphism, which allow a comparison of the (stable and/or metastable) crystal framework.
