Abstract The rattling mode, an anharmonic vibrational phonon, is widely recognized as a critical factor in the emergence of superconductivity in caged materials. Here, we present a counterexample in a filled-skutterudite superconductor Ba$_{x}$Ir$_{4}$Sb$_{12}$ ($x = 0.8$, 0.9, 1.0), synthesized via a high-pressure route. Transport measurements down to liquid $^{3}$He temperatures reveal a transition temperature ($T_{\rm c}$) of 1.2 K and an upper critical field ($H_{\rm c2}$) of 1.3 T. Unlike other superconductors with caged structures, the Ba$_{x}$Ir$_{4}X_{12}$ ($X = {\rm P}$, As, Sb) family exhibits a monotonic decreasing $T_{\rm c}$ with the enhancement of the rattling mode, as indicated by fitting the Bloch–Grüneisen formula. Theoretical analysis suggests that electron doping from Ba transforms the direct bandgap IrSb$_{3}$ into a metal, with the Fermi surface dominated by the hybridization of Ir 5$d$ and Sb 5$p$ orbitals. Our findings of decoupled rattling modes and superconductivity distinguish the Ba$_{x}$Ir$_{4}$Sb$_{12}$ family from other caged superconductors, warranting further exploration into the underlying mechanism.
