A systematic investigation of the structural evolution of the even-even isotones of 40 < Z < 50 nuclei in 50 < N < 60 range of neutron numbers has been done from the calculations of total Routhian surfaces (TRS) in the macroscopic-microscopic formalism. The calculations predict that the nuclei with N = 56 are transitional ones with an onset of deformation at N >= 56. It has been found that the shape of the midshell Ru (Z = 44) isotopes is mostly gamma-soft near the ground state. The TRS calculations at higher rotational frequencies ((h) over line)omega) for Ru-100,Ru-102 show a shape evolution in these nuclei from a prolate-like gamma-soft to a stable triaxial shape. Such stable triaxial shapes in the even-even cores are important to explain the observed chiral bands in the odd-odd Rh nuclei. A common general feature that has been found for the heavier nuclei from this work is the shape invariance of the nuclei with same numbers of total (proton + neutron) valence particles away from N, Z = 50.
