    • The invention relates to novel aminocarboxylate ligands that are suitable for complexing with a radionuclide, and are useful as imaging agents for diagnostic purposes. In accordance with the present invention, a method of preparing a compound of formula (I): fac-[M(CO)3(OH2)3]+, wherein M is Mn, 99mTc, 186Re or 188Re, involves reacting a metal in permetallate form with carbon monoxide and a reducing agent, wherein a mixture of a basic borate buffer and a reducing agent soluble in water but not substantially decomposed by water is solved in a water containing solvent system containing a solution of the metal in permanganate, pertechnetate or perrhenate form in the presence of carbon monoxide. The compound of formula (I) can be reacted with a ligand Lx to form a compound of formula (II): fac-[M(CO)3(X)2L1]n, wherein M is as defined above Lx is a multidentate ligand, and n is a charge of the ligand Lx increased with one + charge. The invention also is directed to novel compounds, and kits for carrying out the disclosed methods.
