We report the synthesis and characterization of an indium-rich quaternary Yb-Pt-In-Bi compound that is similar to the well-known rare-earth transition-metal stannide Remeika-phase compounds. In addition to structural/composition studies identifying the compound as Yb{sub 5}Pt{sub 6}In{sub 16}Bi{sub 2}, we have made dc and ac magnetic susceptibility, specific heat, resistivity, magnetoresistance, Hall effect, and thermoelectric power measurements on this material. It appears that this Remeika-phase compound (structure type Tb{sub 5}Rh{sub 6}Sn{sub 18}) is moderately disordered. Crystal-field effects influence the temperature dependence of the dc magnetic susceptibility, the specific heat, the resistivity, and the thermoelectric power. A cusp in the ac magnetic susceptibility peaks near 300 mK, close in temperature to where the specific heat divided by temperature C{sub p}(T)/T also reaches a maximum. The susceptibility feature is frequency dependent and suggestive of a disorder-induced spin-glass transition rather than conventional magnetic order. {copyright} {ital 1999} {ital The American Physical Society}
