We report extensive measurements on a new compound (Yb0.24Sn0.76)Ru thatcrystallizes in the cubic CsCl structure. Valence band photoemission and L3x-ray absorption show no divalent component in the 4f configuration of Yb.Inelastic neutron scattering (INS) indicates that the eight-fold degenerateJ-multiplet of Yb3+ is split by the crystalline electric field (CEF) into a{\Gamma}7 doublet ground state and a {\Gamma}8 quartet at an excitation energy20 meV. The magnetic susceptibility can be fit very well by this CEF schemeunder the assumption that a {\Gamma}6 excited state resides at 32 meV; however,the {\Gamma}8/{\Gamma}6 transition expected at 12 meV was not observed in theINS. The resistivity follows a Bloch- Gr\"uneisen law shunted by a parallelresistor, as is typical of systems subject to phonon scattering with noapparent magnetic scattering. All of these properties can be understood asrepresenting simple local moment behavior of the trivalent Yb ion. At 1 K,there is a peak in specific heat that is too broad to represent a magneticphase transition, consistent with absence of magnetic reflections in neutrondiffraction. On the other hand, this peak also is too narrow to represent theKondo effect in the {\Gamma}7 ground state doublet. On the basis of thefield-dependence of the specific heat, we argue that antiferromagneticshortrange order (possibly co-existing with Kondo physics) occurs at lowtemperatures. The long-range magnetic order is suppressed because the Yb siteoccupancy is below the percolation threshold for this disordered compound.
