ABS>A number of new B/sub 5/A compounds, with A a rare earth or yttrium and B a transition element, Co, Ni, or Cu, having the Cu/sub 5/Ca structure, were prepared. In most of the compounds, the interatomic distances are normal. However, Ce appears to have a valence substantially greater than three. Also, in Co/sub 5/Pr, Pr appears to have a valence slightly greater than three. (auth)
