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
