Molecular structure of tangdanite from the Jánská vein, Příbram (Czech Republic) - a vibrational spectroscopy study

Popis výsledku v původním jazyce

We have undertaken a study of the copper arsenate sulphate mineral tangdanite from the Jánská vein, Příbram, central Bohemia (Czech Republic). Tangdanite has been found on a few specimens and forms individual radial aggregates up to 3 mm in size composed of platy crystals with perfect cleavage. Tangdanite aggregates usually grow on chrysocolla, or more rarely on hematitized rock. The quantitative chemical analyses of tangdanite agrees well with the proposed ideal composition and corresponds to the following empirical formula: Ca1.96Cu9.01Zn0.02(AsO4)4.06(PO4)0.01 (SO4)0.51(OH)8.76.9H2O (on the basis of 11 cations pfu). Tangdanite is monoclinic, space group C2/c, with unit-cell parameters: a 54.3218(8), b 5.5685, c 10.469 Å, β 96.294o, V 3147.7 Å3; due to strong preferred orientation on sample, only a parameter was refined. The interpretation of Raman and infrared spektra of tangdanite are given in the paper. Raman and infrared spectroscopy confirms absence of (CO3)2- groups in the crystal structure of studied tangdanite.
