System:
Monoclinic
Colour:

Name:
Named in 1828 by Jöns Jakob Berzelius in honor of Wilhelm Hisinger [December 23, 1766 Västmanland, Sweden – June 28, 1852 Skinnskatteberg, Västmanland, Sweden]. Hisinger was a Swedish chemist and mineralogist who worked with Jöns Jakob Berzelius researching electrolysis and the consistency of certain elements to be attracted to similarly charged poles. Hisinger was a co-discoverer of the element cerium, with Berzelius.
Amorphous to poorly crystalline hydrated iron(III) layer silicate.

Compare neotocite and siderogel.
