The ternary system of rare earth elements (Ln) rhodium and boron gives metal cluster compounds with characteristic ionic structure, and the authors have synthesized single crystals of Ln(Rh/sub 4/B/sub 4/), Ln(Rh/sub 3/B), and Ln(Rh/sub 3/B/sub 2/) (Ln = lanthanoid elements in 3+ state). They give not only quite characteristic electric and magnetic properties, but also exhibit remarkable substrate-selective activity as heterogeneous catalyst for hydrogenation of linear olefins. Although alloys containing rare-earth metals and nickel or cobalt have been known to be active for hydrogenation after high-temperature activation by hydrogen under pressure, present crystalline catalysts are unique in their potentiality to be activated at ambient temperature and atmospheric pressure of hydrogen. 5 references.
