In the course of our systematic investigation of the Ce-Pt-Al system a novel ternary intermetallic phase was identified. Compound Ce9Pt25Al37 was synthesized by melting the elemental constituents (purity: Ce 99.85 wt%, Pt 99.99 wt%, Al 99.999 wt%) in an arc-furnace under ultra-pure argon atmosphere. The homogenizing annealing was held in an evacuated quartz tube at 700 º C for 1 month, followed by quenching in cold water. Crystal structure was determined by single-crystal X-ray diffraction with a Nonius KappaCCD diffractometer (MoK¬radiation). The compound crystallizes in the hexagonal space group P m2, lattice parameters: a = 18.6550(5) Å, c = 4.1370(10) Å, Z=1, R1 = 0.045.
