Formula:
Ca8S2(S3)(S2O3)(OH)12 · 20H2O
Crystal System:
Monoclinic
Name:
Named in honor of Alfred Georgievich Bazhenov (Альфред Георгиевич Баженов) (b. 1931), geochemist and petrologist, and his wife, Lyudmila Fedorovna Bazhenova (Людмилы Федоровны Баженовой) (b. 1938), analytical chemist, of the Ilmensky Preserve, Miass, Chelyabinsk Region, Russia.
A mineral with sulphide S2-, trisulphide (S3)2- and thiosulphate (S2O3)2- anions.
However, according to Bindi et al. (2005), the presence of (S2O3)2- anions in bazhenovite is doubtful.
Compare sulfhydrylbystrite.
