Abstract
The packing coefficient is analyzed in orientational disordered phases for a set of series of compounds derived from neopentane [C(CH3)(4)] by means of the substitution of methyl by other groups such as CH2OH, NH2, NO2 and COOH. The packing coefficient, which enables the intermol ecular interactions in the mentioned phases to be accounted for, reach es relatively high values when the interactions generated by means of the dynamical hydrogen bonds are present. The variation of the packing coefficient as a function of the molar fraction in two-component phas e diagrams between the isomorphous and nonisomorphous orientational di sordered phases is also reported in order to understand intermolecular interactions in mixed crystals.
