We investigated the magnetic structure of the heavy fermion compoundCePt$_2$In$_7$ below $T_N~=5.34(2)$ K using magnetic resonant X-ray diffractionat ambient pressure. The magnetic order is characterized by a commensuratepropagation vector ${k}_{1/2}~=~\left( \frac{1}{2} , \frac{1}{2},\frac{1}{2}\right)$ with spins lying in the basal plane. Our measurements didnot reveal the presence of an incommensurate order propagating along the highsymmetry directions in reciprocal space but cannot exclude other incommensuratemodulations or weak scattering intensities. The observed commensurate order canbe described equivalently by either a single-${k}$ structure or by amulti-${k}$ structure. Furthermore we explain how a commensurate-only orderingmay explain the broad distribution of internal fields observed in nuclearquadrupolar resonance experiments (Sakai et al. 2011, Phys. Rev. B 83 140408)that was previously attributed to an incommensurate order. We also reportpowder X-ray diffraction showing that the crystallographic structure ofCePt$_2$In$_7$ changes monotonically with pressure up to $P~=~7.3$ GPa at roomtemperature. The determined bulk modulus $B_0~=~81.1(3)$ GPa is similar to theones of the Ce-115 family. Broad diffraction peaks confirm the presence ofpronounced strain in polycrystalline samples of CePt$_2$In$_7$. We discuss howstrain effects can lead to different electronic and magnetic properties betweenpolycrystalline and single crystal samples.
