A series of technetium complexes with (η⁵-cyclopentadienyl)tris(dimethyl phosphito-P)cobaltate(III), also known as the “Kläui ligand” {L^OMe}⁻, has been prepared. The products span seven different oxidation states (+1 to +7) of the radioactive transition metal and comprise nitrosyl, halide, oxido and nitrido complexes. All members of this series ([Tc^I(NO)Cl(PPh₃)(L^OMe)], [Tc^II(NO)Cl₂(L^OMe)], [Tc^IIICl₂(PPh₃)(L^OMe)], [Tc^IVCl₃(L^OMe)], [Tc^VOCl₂(L^OMe)], [Tc^VNCl(PPh₃)(L^OMe)], [Tc^VINCl₂(L^OMe)], and [Tc^VIIO₃(L^OMe)] are air- and water-stable compounds, which recommends this class of technetium complexes as potential candidates for nuclear medical imaging procedures.

一种配体，一种金属，七个氧化态：稳定的Tech络合物与“Kläui配体”。

用（ηA系列锝配合物的⁵ -环戊二烯基）三（二甲基phosphito- P）钴酸盐（III），也被称为“Kläui配体” {L ^OME } ^-，已被制备。产物涵盖了放射性过渡金属的七个不同的氧化态（+1至+7），并包含亚硝酰基，卤化物，氧化和亚硝基络合物。该系列的所有成员（[Tc ^I（NO）Cl（PPh ₃）（L ^OMe）]，[Tc ^II（NO）Cl ₂（L ^OMe）]，[Tc ^III Cl ₂（PPh ₃）（L ^OMe） ]，[Tc ^IV Cl ₃（L^OMe）]，[Tc ^V OCl ₂（L ^OMe）]，[Tc ^V NCl（PPh ₃）（L ^OMe）]，[Tc ^VI NCl ₂（L ^OMe）]和[Tc ^VII O ₃（L ^OMe）]是空气和水稳定的化合物，建议将这类of配合物用作核医学成像程序的潜在候选物。
