Abstract

A new type of lanthanide transition metal pnictide-oxide, Ln₃Cu₄P₄O₂ (for Ln = La, Ce, and Nd), is reported. The crystal structure is made from Ln₂O₂ layers of the Pb₂O₂ type stacked with layers of Cu₂P₂ tetrahedra. The existence of a homologous series of compounds with similar chemistry connecting the BiCuOSe and ThCr₂Si₂ structure types is indicated. The resistivity of La₃Cu₄P₄O₂ is metallic, with no superconductivity observed above 2 K. The Ce and Nd compounds have magnetic susceptibilities characteristic of the trivalent Lanthanides. The Ce compound orders magnetically at approximately 0.8 K.
