ReClj Rhenium chloride

Treatment of the rhenium sulfide chlorides with an excess of chlorine at temperatures above 450°C results in formation of ReClj (140). Reduction between 350 and 500°C gives binary rhenium chalcogenides (139,262). Action of water vapor on rhenium sulfide chlorides at 350-500°C produces oxysulfides (139). 

As will be discussed in more detail in Chapter 15, there are three distinct bonding mechanisms which contribute to the metal-metal bonding in [C Re-ReC ] ", tr, n and 3 (the chlorines are all terminal and eclipsed), and so it is an anion of particular interest. It is readily prepared from the commercially available ReClj, which consists of molecules containing a triangle of rhenium atoms, by fusion in molten (220 °C) diethylammonium chloride ...
