Comments on the paper on vanadium based double perovskit Ba1.5Sr0.5FeVO6 by S. Bhattacharjee et al. [Materials Science & Engineering B 271, 115,234 (2021)]

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 of Ba2Sr(VO4)(FeO4) instead of Ba1.5Sr0.5FeVO6. Moreover, the symmetry should be trigonal.

Automated summary

This paragraph points out severe errors in the crystallographic part of the commented paper. The actual composition of the crystals studied is unknown, but the diffraction patterns and Rietveld analysis suggest the chemical formula of Ba2Sr(VO4)(FeO4) instead of Ba1.5Sr0.5FeVO6. Moreover, the symmetry should be trigonal.
