About OttohahniteHide

Otto Hahn
yellowish green to greenish-yellow
Crystal System:
To honour Otto Hahn (8 March 1879 – 28 July 1968), German chemist known as the "father of nuclear chemistry", conducting research on radioactivity and radiochemistry, Nobel Prize winner in the field of Chemistry in 1944 as the discoverer of nuclear fission.
Related to klaprothite and péligotite.

Also chemically related to fermiite and oppenheimerite.

Further relation to sulfate-hydrosulfates belakovskiite and meisserite, and to basic salts plášilite and natrozippeite.

Found together with péligotite and klaprothite; the three minerals are very similar in terms of physical and chemical properties (colour, fracture, hardness, water solubility, fluorescence).

The structure is based on [(UO2)4(SO4)10]12– clusters (different from those in klaprothite and péligotite), with each UO7 polyhedron having a bidentate linkage with one sulphate tetrahedra. Na-O polyhedra provide two types of linkages: (1) for the clusters, to give thin heteropolyhedral slices, and (2) between the slices, to form the framework.
