Dear Armel,
obviously the structure of bazhenovite is unknown (although bright
orange to yellow, tabular xls up to 5 mm were reported).
The mineral is said to be the monoclinic analog of the synthetic
rhombic compound CaS5.CaS2O3.6Ca(OH)2.20H2O (Lutz, H. D.
et al, 1969).
I don't know about the stability - maybe it's discussed in the
original publication. I could give you the contact address of a
Russian colleague who should know more about this mineral
(contact me off-list then).
Regards, Uwe
