American Mineralogist (1990) 75 (11-12): 1415–1420.
... imply that montesommaite is related to merlinoite (K 5 Ca 2 Al 9 Si 23 O 64 · 24H 2 O) and to the members of the gismondine group. This suggestion is verified by a determination of the idealized substructure of montesommaite in 14,/amd symmetry using powder diffraction intensities. Copyright © 1990...
