Electron-phonon coupling in $\mathrm{Zr}{\mathrm{Co}}_{2}\mathrm{Sn}$ is investigated within the density-functional theory and linear-response approach mixed-basis pseudopotential representation. Phonon-induced scattering analyzed for excited electrons (holes) two majority bands, which form topological Weyl state. Although electron-phonon energy range under consideration demonstrates some dependence on available phase space, strength of phonon-mediated scattering, $\ensuremath{\lambda}$, changes rather weakly with hole (electron) momentum, varying between 0.1 0.3. The momentum-averaged value $\ensuremath{\lambda}$ ranges from 0.25 to 0.45. near point found be weak enough warrant well-defined quasiparticles. Most modes actively involved electron are middle- high-frequency lattice vibrations, while participation low-energy acoustic phonons significantly suppressed by matrix elements. Of long-wavelength optical phonons, only ${T}_{2g}$ Raman active generated opposite vibrations Co atoms make a noticeable contribution electrons.
