Abstract
The literature data on equilibrium with the participation of cobalt fluorides and their negative ions are analyzed. Enthalpies of formation −∆fH°(0 K) are determined (kJ/mol): CoF3, 568.9 ± 8; \({\text{CoF}}_{3}^{ - }\), 972.4 ± 10; CoF4, 639.4 ± 12; \({\text{CoF}}_{4}^{ - }\), 1228.0 ± 17.
