RADIOACTIVE TECHNETIUM AND RHENIUM NITRIDE HETEROCOMPLEXES

摘要

One of radioactive transition metal nitride hetero-complexes which can label physiologically active substances such as peptides or hormones without impairing the activities thereof. It is composed of a radioactive transition metal nitride and two different ligands coordinating to the nitride, and is represented by the following general formula (I): (M.ident.N)XY, wherein the radioactive transition metal, M, is radioactive technetium or rhenium; N is nitrogen; X is a diphosphine compound or a diarsine compound; and Y is a bidentate ligand having a combination of electron-donating atoms.
