In our current work attempts have been made for the comparative theoretical study on the phase transition of complex compounds of heavy metal halides AgxCu1-xI and CuxRb1-xI due to high pressure for the different values of x. The current work uses the technique of two body potential model involving the long range Coulomb’s electrostatic forces, vander Waal’s forces and short range repulsive forces. This model has been used to determine the phase transition pressure, volume collapses and Gibb’s free energy in terms of pressure for Zinc-Blende and tetragonal structure. This comparative investigating work tries to emphasize on the stability of complex crystal structures and its wide field of applicability.

Gibb’s eneergy, Zinc-Blende structure, vander Waal’s force, Coulomb’s force, volume collapse, Born-Mayer potential, Philipse criteria.
