Superconducting transition temperatures calculated with the Allen–Dynes formula (\({T}_{{{{\rm{c}}}}}^{\,{{{\rm{AD}}}}}\) in K) above 4.2 K, logarithmic average of the phonon frequencies (\({\omega }_{\log }\) in K), and the electron–phonon coupling constant (λ) for vacancy-ordered double perovskites. The ALIGNN-predicted \({T}_{{{{\rm{c}}}}}^{{{{\rm{pred}}}}}\) (K) are included in the last column for comparison with \({T}_{{{{\rm{c}}}}}^{\,{{{\rm{AD}}}}}\).
