An equimolar combination of n-C28H58/n-C32H66/n-C36H74, crystallized from the melt, initially forms a solid solution. Electron diffraction data from the epitaxially oriented [100] projection can be used to determine its crystal structure, a pseudo n-C33H68 layer in space group A2(1)am (a = 7.42, b = 4.96, c = 87.40 Angstrom). After 6 days at room temperature, a superlattice is formed (c = 351.1 Angstrom). Its crystal structure, suggested from the direct Fourier transform of 00l reflections, is a sequence of solid solution lamellar, layers. After 16 months, another superlattice is observed with a spacing double the one found earlier. Its crystal structure appears to be a sequence of nearly pure n-alkane chain layers. While the behavior resembles the case of n-C30H62/n-C36H74 solids, where n-C28H58/n-C32H66 1:1 is a pseudocomponent, the sequence of phase separation within the miscibility gap is more complicated than that of the binary combination.
