Crystal structure and characterization of CePt₂In₇. (a) Crystal structure of CeIn₃. (b) Crystal structure of CeMIn₅ (M = Co, Rh, and Ir) with a space group P4/mmm. (c) Crystal structure of CePt₂In₇ with a space group I4/mmm, formed with CeIn₃ layers separated by PtIn₂ layers. (d) X-ray diffraction patten of our CePt₂In₇ single crystal. The inset shows the image of the surface of a cleaved CePt₂In₇ sample with a size of 1 mm × 0.8 mm. (e) Laue diffraction image of our CePt₂In₇ sample.
