New insight into the reduction of rhenates(VII) with hydrogen chloride and into the structure of the ReOCl5- product

Rhenate(VII) anion is reduced by gaseous HCl to yield pentachloridooxidorhenate(VI) anion. Several pentachloridooxidorhenate(VI) salts have been crystallized and the anion structure has been investigated in detail. The ReOCl5- anion structure has been compared with the ReOCl52- structure and conclusions concerning the influence of the central atom d electrons number on the anion geometry have been drawn.
