Abstract

K2ReCl6 (IV), after precipitation from solutions of HCl36 with nitron, contained no significant radioactivity. Cs2ReOCl5 (V), insoluble in HCl, after suspension in methanol containing HCl36 and filtration was radioactive. An x-ray diffraction determination of the Cs2ReOCl6 unit cell parameters and a microscopic estimation of the surface of the samples made possible the calculation of 83% exchange of the surface chlorine atoms. Results agree with the generalization that octohedral complexes with no vacant d orbitals are inert, whereas those with at least one vacant d orbital are labile. Cs2ReOCl5 is a yellow-brown crystalline solid, insoluble in dilute HCI. X-ray diffraction determination gave hexagonal unit cell parameters of a =7.04A0 and C=10.9A0
