Abstract

The syntheses of La5Cu19P12 and Ce5Cu19P12 are reported, as is the crystal structure of La5Cu19P12, determined by single crystal X-ray diffraction. The compounds are found to be of the Sc5Co19P12 structure type. Both new materials are metallic, with the resistivity of Ce5Cu19P12 characteristic of heavy fermion behavior. The magnetic susceptibility of Ce5Cu19P12 shows the signature of a crystal electric field (CEF) split 4f multiplet for Ce, with a high temperature effective moment of Peff = 1.71(2) μB/mole Ce. For La5Cu19P12, no local moment is observed for copper.
