An appraisal of Understanding Pressure Effects on Structural, Optical, and Magnetic Properties of CsMnF_{4} and Other 3d^{n} Compounds

Abstract

A recently published article in Inorganic Chemistry (DOI: 10.1021/acs.inorgchem.4c00599) offers theoretical calculations on the effects of pressure on the structural, optical, and magnetic behavior of CsMnF_{4}. Although a thorough theoretical and experimental understanding of this material is certainly warranted, there are previously published experimental results on CsMnF_{4}, as well as on other Mn^{3+} fluorides, under pressure that have not been considered in the aforementioned article. These findings raise questions about the accuracy of the theoretical estimates and the validity of the methodology used to determine the reported structural, optical, and magnetic properties. This paper intends to provide the readers of Inorganic Chemistry and the broader scientific community with a perspective on a publication that directly contradicts interpretations presented in prior research.
