Of technetium compounds

All the current methods of synthesizing of technetium compounds (as well as most compounds of other metals [1,11]) with M-M bonds involve reductions of complexes of the central atom in the higher oxidation states with further (or...

Decacarbonylditechnetium, Tc2(CO)io, requires some special precautions since technetium is a /3-emitter. Tc2(CO)io has been proposed as the starting material for the preparation of technetium compounds with potential radiopharmaceutical properties. The original method of preparing Tc2(CO)io consists of treating the heptoxide, TC2O7, with CO under pressure (250 350 atm) at 220-275 °C (equation 9 M = Tc). ...

The structures of technetium compounds are insufficiently known to give satisfactory values for ionic radii. Its covalent radius is very little less than that of rhenium both metals have the same crystal structure (h.c.p.) and the atomic volume of Re is very little greater (p. 480).
