Abstract
Technetium-99m complexes of crown thioethers having 3 to 6 donor sulphur atoms joined into a macrocyclic ring by C2 or C3 groups, for example 1,4,7-trithiacyclononane (9S3); and of tripodal ligands having more than 3 donor sulphur atoms joined by C2 or C3 groups, for example, 1,1,1-tris(((2-methylthio)ethylthio)-methyl)ethane.
Claims7
A Technetium complex of a crown thioether having 3 to 6 donor sulphur atoms joined into a macrocyclic ring by ethylene or trimethylene groups.
A Technetium complex of a 1,1,1-substituted ethane in which each of the three substituents contains at least one sulphur atom having more than three donor sulphur atoms joined by ethylene or trimethylene groups.
