The Raman and infrared spectrum of the antimonate mineral stibiconite [image omitted] were used to define aspects of the molecular structure of the mineral. Bands attributable to water, OH stretching and bending, and SbO stretching and bending were assigned. The mineral has been shown to contain both calcium and water and the formula is probably best written Sb3+Sb25+O6(OH) (O,OH,H2O)(6-7) where y approaches 1 and x varies from 0 to 1. Infrared spectroscopy complimented with thermogravimetric analysis proves the presence of water in the stibiconite structure. The mineral stibiconite is formed through replacement of the sulphur in stibnite. No Raman or infrared bands attributable to stibnite were indentified in the spectra.
