    • Abstract

       

      Powder XRD data of mixtures of title compounds are interpreted in terms of superlattices (SL). It is suggested that SL configurations (orthorhombic-orthorhombic, orthorhombic-monoclinic, monoclinic-monoclinic) are realizable, because of discrete orientational changes in the alignment of molecules of n-C28H58 hydrocarbon, through an angle mθ, wherem = 1, 2, 3 … and angle θ has an average value of 3.3°. Supporting literature evidence on the inclinations are discussed.
