    Abstract: In this paper we report that there exists a structural phase transition between cubic and tetragonal superconductors. Calculation of the transition temperature TM is performed with a half-filled doubly degenerate eg-band using BCS mean field theory. It is found that the transition temperature TM between the two superconductors reduces to that of the ordinary structural phase transition if the energy gap A is zero.
