Binuclear carbonyl complexes with M—M bond analogous to Mn2(CO)io have been prepared for technetium and rhenium. The rhenium analogue has been synthesized by the carbon monoxide reduction of Rc207 or KRe04 (eq (5)) [3] or by reduction of anhydrous Re(III) or Re(V) chloride by sodium under CO pressure (eq (6)). [15]. The physical and structural properties of Tc2(CO),o and Re2(CO)io are listed in Table 9.1.
