1938 Amer. Mineralogist 23 745 On dehydration..hohmannite apparently loses the four loosely held molecules of water and forms what is here called metahohmannite. In this respect it differs from amarantite, which is much more stable under atmospheric conditions.
1968 I. Kostov Mineral. 499 Amarantite and hohmannite are triclinic~pinacoidal.
