We have shown that the value of Coulomb pseudopotential ($\\mu^{\\star}$) for ${\\rm H_{5}S_{2}}$ ($\\left[T_{C}\\right]_{\\rm exp}=36$~K and $p=112$~GPa) is anomalously high. The numerical results give the limitation from below to $\\mu^{\\star}$ that is equal to $0.402$ ($\\mu^{\\star}=0.589$, if we consider the first order vertex corrections to the electron-phonon interaction).
