Ab initio calculations of the electronic structure and lattice-vibrational properties were performed on the superconducting high-temperature polymorphs of YIr2Si2 and LaIr2Si2. The electron-phonon coupling constants ep were found to be 0.61 and 0.56 for YIr2Si2 and LaIr2Si2, respectively. The superconducting critical temperatures estimated from the Allen-Dynes formula agree well with the available experimental data and indicate that the superconductivity in these compounds can be explained by intermediate strength electron-phonon coupling.
