We report the synthesis, structure, and physical properties of single crystals of CePt2In7. Single crystal x-ray diffraction analysis confirms the tetragonal I4/mmm structure of CePt2In7 with unit cell parameters a = 4.5886(6) Å, c = 21.530(6) Å and V = 453.32(14) Å3. The magnetic susceptibility, heat capacity, Hall effect and electrical resistivity measurements are all consistent with CePt2In7 undergoing an antiferromagnetic order transition at TN = 5.5 K, which is field independent up to 9 T. Above TN, the Sommerfeld coefficient of specific heat is γ ≈ 300 mJ mol−1 K−2, which is characteristic of an enhanced effective mass of itinerant charge carriers. The electrical resistivity is typical of heavy-fermion behavior and gives a residual resistivity ρ0 ~ 0.2 µΩ cm, indicating good crystal quality. CePt2In7 also shows moderate anisotropy of the physical properties that is comparable to structurally related CeMIn5 (M = Co, Rh, Ir) heavy-fermion superconductors.
