摘要：

The crystal structures have been solved and/or refined for minerals of the alunite and beudantite groups having the general formula AM(3)(XO4)(2)(OH)(6): that is, Pb(Fe2Cu)(SO4)(2)(OH)(6) [beaverite], PbFe3(SO4)(PO4)(OH)(6) [corkite], KAl3(SO4)(2)(OH)(6) [alunite], NaAl3(SO4)(2)(OH)(6) [natroalunite], KFe3(SO4)(2)(OH)(6) [jarosite], SrAl3(SO4)(PO4)(OH)(6) [svanbergite] and CaAl3(SO4)(PO4) (OH)(6) [woodhouseite]. The structure analyses revealed that the ionic radius Of the M site cation affected the a axis length whereas those of the A and X site ions influenced the c axis length. Cu-bearing minerals, osarizawaite and beaverite, showed the Jahn-Teller distortion in the Cu2+ octahedra. The space group of corkite was found to be the centric R (3) over barm rather than the acentric R3m space group reported previously.
