European Journal of Mineralogy (December 1994) 6 (6): 887-896


Uralolite from the Weinebene, Koralpe, Carinthia, Austria, is monoclinic, space group P2 (sub 1) /n, with a 6.550, b 16.005, c 15.969 Aa, beta 101.64 degrees , V 1639.6 Aa (super 3) , Z = 4. The structure was refined to R 0.058; it exhibits a novel type of corrugated tetrahedral layer (010). This layer is of composition [Be (sub 4) (PO (sub 4) ) (sub 3) (OH) (sub 3) ] (super 4+) and contains S-shaped groups of four corner-sharing BeO (sub 4) tetrahedra which link with PO (sub 4) tetrahedra to form 3-, 4- and 8-membered rings, including the first occurrence of a BeBeBeP ring. Two Ca atoms in CaO (sub 5) (H (sub 2) O) (sub 2) coordination and a 'free' water molecule complete the structure, which is pseudosymmetric and approximates to space group C2/c.
