Abstract
Tridentate mono-anionic ligands have the structure EQU X-A-Y-Q-Z where each of X and Y is independently P, As or N, PA1 Z is phenol, thiophenol or thiol, and PA1 A and Q are hydrocarbon linking groups. The ligands from cationic complexes with Technetium-99m, e.g. [Tc.sup.III K.sub.2 ].sup.+ where K is the ligand, having useful imaging properties.
