Technetium Complexes with Triazacyclononane

Inorganic Chemistry, 2006
[NBu4][TcOCl4] reacts with ethylene glycol and 1,4,7-triazacyclononane (tacn) in MeOH under the formation of the deep-blue oxotechnetium(V) cation [TcO(OC2H4O)(tacn)]+, which can readily be oxidized by air to give the stable technetium(VII) compound [TcO3(tacn)]+.

Technetium, the missing element

European Journal of Nuclear Medicine, 1996
The history of the discovery of technetium is reviewed within the framework of the discovery and production of artificial radioactivity in the twentieth century. Important elements of this history are the accidental production of this element in a cyclotron in Berkeley, California, USA, a machine devised by Ernest Orlando Lawrence, and its subsequent ...

The composition and structure of technetium nitride and technetium borides

Journal of the Less Common Metals, 1964
Analysis of Tc heated in nitrogen in the temperature range 400 -900 deg C revealed no change in the lattice constants of the metal. When heated in ammonia in the range 7001100 deg C, lattice constants increased to an extent depending on the amount of nitrogen absorbed.

Chemistry of technetium 99m

Seminars in Nuclear Medicine, 1974
The detection of a number of impurities in 99m Tc effluents from 99 Mo generators is important for proper use of the generator systems. Their identification is described in this review. Technetium in sulfur colloid is probably present as Tc 2 S 7 .

[Technetium polyphosphate and technetium diphosphonate. A comparative study].

Nuclear-Medizin, 1975
99mTc-labelled phosphates are the bone seeking agents of choice. The comparison of 99mTc-polyphosphate (Poly-P) and 99mTc-ethane-1-hydroxy-1,1-diphosphonate (EHDP) shows a better in vitro stability of the latter during the first two hours after preparation.
