I have .cif files of the Na2S hydrates (n=0, 5 and 9). I miss info about other hydrates and I am especially interested in the dihydrate. Does anybody has the .cif files or have literature sources?
Hi, H.P.!
I cannot find any structure, but I have a reference you can investigate further. Perhaps it is of interest:
"Mechanisms and kinetics of the thermal decomposition of sodium sulphide pentahydrate under controlled water vapour pressure"; Jan Y. Andersson & Michel Azoulay; J. Chem. Soc., Dalton Trans., 1986, 469-475. [DOI: 10.1039/DT9860000469]

I suggest checking the ICSD and ACS websites. Though when i did a quick search on the ICSD website, there were no Na2S dihydrate phases (nor nonahydrate, so it doesn't mean they don't exist...)
Hi, Pieter!
Actually, the nonahydrate is listed in ICSD as structure #26795. The dihydrate is not listed, however.
regards,
Daniel
