The minerals of the mixite group—zálesíite CaCu 6 [(AsO 4 ) 2 (AsO 3 OH)(OH) 6 ]·3H 2 O from abandoned uranium deposit Zálesí, Czech Republic and calciopetersite CaCu 6 [(PO 4 ) 2 (PO 3 OH)(OH) 6 ]·3H 2 O from a quarry near Domašov na Bystřicí, northern Moravia, Czech Republic—were studied by Raman and infrared spectroscopy. The observed bands were assigned to the stretching and bending vibrations of (AsO 4 ) 3− and (AsO 3 OH) 2− ions in zálesíite, and (PO 4 ) 3− and (PO 3 OH) 2− in calciopetersite, and to molecular water, hydroxyl ions, and Cu‐(O,OH) units in both minerals. OH···O hydrogen‐bond lengths in zálesíite and calciopetersite structures were calculated with Libowitzky's empirical relation. Copyright © 2010 John Wiley & Sons, Ltd.
