Preparation and characterization of Zn(II), Cu(II), and Fe(III) fluorosulfates

Abstract

Zinc, cupric, and ferric fluorosulfates have been prepared. The Raman and infrared spectra of potassium fluorosulfate and the infrared spectra of calcium, zinc, cupric, and ferric fluorosulfates have been measured from 33 to 4 000 cm−1. Evidence for covalent bonding in the cupric and ferric fluorosulfates has been found. The magnetic properties of cupric and ferric fluorosulfates have been studied, and ferric fluorosulfate has been found to be magnetically concentrated. The thermal decomposition of zinc, cupric, and ferric fluorosulfates is reported.
