Abstract

A new type of lanthanide transition metal pnictide oxideLn₃Cu₄P₄O₂(forLn=La, Ce, and Nd), is reported. The crystal structure is made fromLn₂O₂layers of the Pb₂O₂type stacked with layers of Cu₂P₂tetrahedra and indicates the existence of a homologous series of compounds with similar chemistry connecting the BiCuOSe and ThCr₂Si₂structure types. The resistivity of La₃Cu₄P₄O₂is metallic, with no superconductivity observed above 2 K. The Ce and Nd compounds have magnetic susceptibilities characteristic of the trivalent Lanthanides. No magnetic ordering is observed above 4.2 K.
