Naphthalene + 2-fluoronaphthalene system: unit-cell parameters (in Å and °) measured at room temperature as a function of mole fraction for pure naphthalene and related mixed crystals (filled triangles, type 2 packings) and for pure 2-fluoronaphthalene and related mixed crystals (filled ellipses, type 1 packings). Extrapolation proposed for the metastable form of 2-fluoronaphthalene (open ellipses, type 2 packing). |
