Rhenium xanthate structures

There are three rhenium xanthate structures in the literature and two of these are binuclear. The mononuclear complex of formula (Me5C5)ReCl3(S2COCy) (46) is represented in Fig. 26. The rhenium atom is considered to exist in a... 

No binary xanthate structures of manganese, technetium, or rhenium have been reported. Indeed, there are relatively few crystal structures known with only a single manganese structure (two polymorphs), two phosphine adducts of technetium and three structures containing rhenium, two of which are dinuclear.
