  In a recent paper [T. Shang et al., Phys. Rev. B 107, 224504 (2023)], the
authors study the physical properties of TaReSi compounds having Ima2
structure. This noncentrosymmetric structure is proposed to be the source of
topological properties for mentioned compound. However, for a correct
description of topological features, it is important to recognize the correct
structure of the compound at low temperature. In this Comment, we show that
Ima2 cannot be realized by TaReSi and is unstable at low temperature. The Ima2
structure contains the soft modes at S (1/2,0,0) point, which leads to the
stable structure with Cm symmetry. Notably, the stable Cm system also has a
noncentrosymmetric structure, which can be the actual source of topological
properties.
