Prossima pubblicazione.

▪ Elliott, P. (2017): Refinement of the crystal structure of sieleckiite and revision of its symmetry. Mineralogical Magazine, 81, (in press).

Abstract:
The crystal structure of the copper aluminium phosphate mineral sieleckiite, Cu3Al4(PO4)2(OH)12·2H2O, from the Mt Oxide copper mine, Queensland, Australia was solved from single-crystal X-ray diffraction data utilising synchrotron radiation. Sieleckiite has monoclinic rather than triclinic symmetry as previously reported and is space group C2/m with unit-cell parameters a = 11.711(2), b = 6.9233(14), c = 9.828(2) Å, β = 92.88(3)º, V = 795.8(3) Å3 and Z = 2. The crystal structure, which has been refined to R1 = 0.0456 on the basis of 1186 unique reflections with Fo>4σF, is a framework of corner-, edge- and face-sharing Cu and Al octahedra and PO4 tetrahedra.
