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

Abstract 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 View the MathML sourceReOCl5- anion structure has been compared with the View the MathML sourceReOCl52- structure and conclusions concerning the influence of the central atom d electrons number on the anion geometry have been drawn.
