The crystal structures of lavendulan from the Hilarion mine, Laurion, Greece, and isotypic sampleite from the Northparkes mine, New South Wales, Australia, have been determined from single-crystal diffraction data, resulting in a revision of the symmetry. The structure of lavendulan, NaCaCu 5 (AsO 4 ) 4 Cl · 5H 2 O (space group P 2 1 / n , a = 10.011(1), b = 19.478(2), = 10.056(1) A, β = 90.37(1)°, V = 1960.8(3) A 3 , Z = 4) was solved from X-ray data (Mo K , CCD area detector) and refined to R… Expand

A near-infrared and Raman spectroscopic study of the mineral richelsdorfite Ca2Cu5Sb[Cl|(OH)6|(AsO4)4]·6H2O.
Raman spectroscopy has enabled insights into the molecular structure of the richelsdorfite mineral, based upon the incorporation of arsenate or phosphate with chloride anion into the structure and as a consequence the spectra reflect the bands attributable to these anions, namely arsenates or phosphate and chloride.
