Technetium-99m complexes of thioethers having 3 to 6 donor sulfur atoms joined in a macrocylic nucleus by C2 or C3 groups, for example 1,4,7-trithiacyclononane (9S3) as well as tripod ligands having more than 3 atoms sulfur donors joined by C2 or C3 groups, for example 1,1,1-tris (((2-methylthio) ethylthio) -methyl) ethane. |
