Abstract

The crystal structure of seelite from Rabejac has been determined to R 0.031; a 18.194, b 7.071, c 6.670 Aa, beta 99.70 degrees , V 845.8 Aa (super 3) , space group C2/m, D 3.71, Z = 2 Mg[(UO (sub 2) )(AsO (sub 3) ) (sub 0.07) (AsO (sub 4) ) (sub 0.3) ] (sub 27H) (sub 2) O. The structure consists of layers similar to those of the seelite from Talmessi [Min.Rec. 24-463] and those of the silicates of the uranophane structural group. Those layers are connected by octahedral Mg(H (sub 2) O) (sub 6) cations and by water molecules. The uranyl phosphate ranunculite [M.M. 43-321] is probably isostructural with seelite.
