1941 C. Frondel in Amer. Mineralogist 26 303 The hexagonal mineral commonly admixed with pyroaurite is described on a following page under the name sjögrenite.

1968 Acta Crystallographica B. XXIV. 972/1 The carbonate-hydroxides Mg₆M₂^III(OH)₁₆CO_3·4H₂O (M^III = Fe, Al, or Cr) are known to occur in two dimorphic forms: the hexagonal sjögrenite group has a ∼ 3·1 and c ∼ 15·5 Å; the rhombohedral pyroaurite group has the same a value but c is about 23·2 Å.

1973 Mineral. Mag. 39 378 Two sub-groups could be distinguished, which would today be described as polytypes differing only in layer stacking; these are represented by pyro~aurite and sjögrenite respectively.
