The heating of Re3I3Br6 up to 450 ◦C led to the formation of Re3Br9. Carbonylation of Re3Br9 with HCOOH at 130◦С in concentrated HBr leads to the formation of Re(CO)5Br in a good yield. The formation of Re3Br9 and Re (CO)5Br was confirmed by single crystal X-ray diffraction analysis. The cluster phase Re3Br9 was characterized by powder X-ray diffraction analysis and energy-dispersive spectroscopy. Re(CO)5Br was additionally identified by energy-dispersive spectroscopy and Raman spectroscopy. New structures have been determined for an aquation product of Re3Br9, [Re3Br9(H2O)3]⋅3Et2O, and for (PyH)2ReBr6, which was obtained as pyridinium by extraction with HBr of a by-product of the thermal decomposition of Re3I3Br6. Re3I3Br6 was characterized by thermogravimetric analysis.
