摘要: Recently several natural and artificial ferric iron sulphate crystal structures have been solved. Sideronatrite, Na2Fe3+(SO4)2(OH)·3H2O, does not provide good crystals for structural purposes. However if we examine crystallographic, chemical physical data some useful information about the ...Fe−O−S... topology can be inferred. In fact this analysis strengthens hypothesis that there is a {Fe 2 3+ (SO4)4(OH)2} chain in sideronatrite like found guildite, Cu2+Fe3+(SO4)2(OH)·4H2O.
