β¦ Synopsis
Crystal Structure and Magnetic Properties of Ce 7 Ni 5Β±x Ge 3Β±x In 6 and Pr7Ni5Β±xGe3Β±xIn6. -Ce7Ni4.73Ge3.27In6 and Pr7Ni4.96Ge3.04In6 are prepared by arc-melting of the elements and characterized by single crystal XRD and magnetic measurements. The compounds crystallize in the space group P6/m with Z = 1. The new structure type can be derived from the AlB2-type structure by substitution of the Al and B atoms by CeM 12 (M: Ge/Ni) hexagonal prisms an tricapped trigonal prismatic NiIn 6 Ce 3 polyhedra. Polycrystallin Ce7Ni5Ge3In6 shows Curie-Weiss like paramagnetic behavior down t 1.
