Seifert S, Kunstler JU, Schiller E, Pietzsch HJ, Pawelke B, Bergmann R, Spies H: Novel procedures for preparing 99mTc (III) complexes with tetradentate/monodentate coordination of varying lipophilicity and adaptation to 188Re analogues. Bioconjug Chem. 2004 Jul-Aug;15(4):856-63.
At first the Tc (III)- or Re (III)-EDTA complex is formed which reacts in a second step with the tripodal ligand 2,2',2' '-nitrilotris (ethanethiol) (NS3) or its carboxyl derivative NS3COOH (a) and the monodentate phosphine ligands (triphenylphosphine L1, dimethylphenylphosphine L2) or isocyanides (tert-butyl isonitrile L3, methoxyisobutyl isonitrile L4, 4-isocyanomethylbenzoic acid-L-arginine L5, 4-isocyanomethylbenzoic acid-L-arginyl-L-arginine L6, 4-isocyanomethylbenzoic acid-neurotensin (8-13) L7) to the so-called '4+1' complex. |

Conradie J, Quarless DA Jr, Hsu HF, Harrop TC, Lippard SJ, Koch SA, Ghosh A: Electronic structure and FeNO conformation of nonheme iron-thiolate-NO complexes: an experimental and DFT study. J Am Chem Soc. 2007 Aug 29;129(34):10446-56. Epub 2007 Aug 8.
The greater instability of the {FeNO}(7) state with the PS3* ligand results from a stronger antibonding interaction involving the metal d (z (2)) orbital and the phosphine lone pair than the analogous orbital interaction in the NS3 case. |
