Here, we report the discovery of superconductivity in pressurized CeRhGe3, a nonsuperconducting member of the isostructural family of noncentrosymmetric heavy-fermion compounds CeTX3(T = Co, Rh, Ir and X=Si, Ge). Superconductivity appears in CeRhGe3 at a pressure of 19.6 GPa and the transition temperature TC reaches a maximum value of 1.3 K at 21.5 GPa. This finding provides an opportunity to establish systematic correlations between superconductivity and material properties within this family. Though ambient-pressure unit-cell volumes and critical pressures for superconductivity vary substantially across the series, all family members reach a maximum TmaxC at a common (±1.7%) critical cell volume Vcrit, and TmaxC at Vcrit increases with increasing spin-orbit coupling strength of the d electrons. These correlations show that substantial Kondo and spin-orbit couplings favor superconductivity in this family, the latter reflecting the role of broken centrosymmetry.
