Here, we report thermoelectric properties of Ir1–xRhxTe2 (0 ≤ x ≤ 0.3) alloy series where superconductivity at low temperatures emerges as the high-temperature structural transition (Ts) is suppressed. The isovalent ionic substitution of Rh into Ir has different effects on physical properties when compared to the anionic substitution of Se into Te, in which the structural transition is more stable with Se substitution. Rh substitution results in a slight reduction of lattice parameters and in an increase of number of carriers per unit cell. Weak-coupled BCS superconductivity in Ir0.8Rh0.2Te2 that emerges at low temperature (Tczero = 2.45K) is most likely driven by electron-phonon coupling rather than dimer fluctuations mediated pairing.
