Revision of the Mg(ClO4)2·4H2O crystal structure

A revision is presented of the restrained Rietveld analysis of the crystal structure of magnesium perchlorate tetrahydrate, Mg(ClO4)2·4H2O, recently published by Robertson & Bish [(2010), Acta Cryst. B66, 579584]. The actual symmetry of the material is shown to be C2/m. The corrected structure m...

Zusammenfassung:	A revision is presented of the restrained Rietveld analysis of the crystal structure of magnesium perchlorate tetrahydrate, Mg(ClO4)2·4H2O, recently published by Robertson & Bish [(2010), Acta Cryst. B66, 579584]. The actual symmetry of the material is shown to be C2/m. The corrected structure model is refined by the derivative difference method [Solovyov (2004). J. Appl. Cryst.37, 743–749], anisotropically for all non‐H atoms and isotropically for two independent H atoms without restraints.
