Comments on the paper on vanadium based double perovskite BaSrFeVO6 by S. Bhattacharjee et al. and published in Mat. Sci. Semicon. Proc. 123 (2021) 105503

My comments concern the severe errors in the crystallographic part of the commented paper. The actual composition of the studied crystals is not known, but the diffraction patterns and Rietveld analysis suggest the chemical formula to be Ba2Sr(VO4)(FeO4) instead of BaSrFeVO6. Moreover, the symmetry should be trigonal.

Automated summary

This comment highlights severe errors in the crystallographic part of the commented paper, pointing out the need for corrections in the composition and symmetry of the studied crystals.
