Abstract: We demonstrate experimentally that the intermetallic compound Ce${\mathrm{Ru}}_{2}$${\mathrm{Si}}_{2}$ exhibits low-temperature magnetic properties similar to those of the heavy-fermion superconductor Ce${\mathrm{Cu}}_{2}$${\mathrm{Si}}_{2}$. Magnetic susceptibility and $^{29}\mathrm{Si}$ nuclear magnetic resonance (NMR) measurements establish that the ground state of Ce${\mathrm{Ru}}_{2}$${\mathrm{Si}}_{2}$ is nonmagnetic, and electrical resistivity measurements reflect Kondo-type spin fluctuations. The observed proportionality between the Ce contributions to the $^{29}\mathrm{Si}$ NMR shift $K$ and the magnetic susceptibility $\ensuremath{\chi}$ distinguishes Ce${\mathrm{Ru}}_{2}$${\mathrm{Si}}_{2}$ from mixed-valence Ce- and Yb-based systems found previously to exhibit anomalous nonlinear dependence of $K$ on $\ensuremath{\chi}$.
