Electron-concentration and pressure-induced structural transitions in solid solutions In1–xCdx (0<=x<=0.1) and In1–xSnx (0<=x<=0.2) have been investigated by means of first principles calculations. At ambient pressure the structural sequence face-centered cubic --> body-centered tetragonal (c/a>sqrt(2)) --> body-centered tetragonal (c/a<sqrt(2)) is realized with increasing of valence electron concentration (VEC). High pressure has the same effect as the increase of electron concentration shifting the occurrence of the structural transitions to lower-valence electron concentration. The driving force behind the peculiar structural sequence is an enhancement of s-p hybridization with increasing VEC.
