Single crystals of Ce 5 Pb 3 O have been synthesized by flux growth. This compound adopts the tetragonal I 4/ mcm space group with lattice parameters of a = b = 8.5870(2) Å and c = 14.3870(5) Å, Z = 4. The crystal structure of Ce 5 Pb 3 O consists of a network of interpenetrating corner-sharing Ce-centered Pb 6 octahedra and O-centered Ce 4 tetrahedra. The tetrahedra are linked to each other by Pb trigonal antiprisms. Magnetization measurements show that Ce 5 Pb 3 O orders ferrimagnetically at T c = 46 K, the second-highest known ordering temperature for any Ce-based intermetallic compound.
