Summary

The authors describe two new phases that form in the lutetium-nickel-boron-carbon system: lutetium-nickel(2)-boron(2)-carbon, a superconductor with a critical temperature of 16.6 K, and lutetium-nickel-boron-carbon, a closely related non-superconducting phase. The superconductor is a variant on the layered thorium-chromium(2)-silicon(2)-type structure, with additional carbon in the lutetium plane. Lutetium-nickel-boron-carbon is derived from lutetium-nickel(2)-boron(2)-carbon by adding another layer of lutetium-carbon, producing a sodium chloride-type intergrowth. A new homologous series of intermetallic phases may be derivable from the simple building principles of these two structures.
