The present invention provides a single radioactive transition metal nitride heterocomplex which permits labeling of a physiologically active substance such as a peptide, hormone or the like without impairing the activity of the substance. The radioactive transition metal nitride heterocomplex of the present invention is represented by the following formula (I):
(M═N)XY (I)
wherein a radioactive transition metal M is radioactive technetium or radioactive rhenium, N is a nitrogen atom, X is a diphosphine compound or a diarsine compound, and Y is a bindentate ligand having a combination of electron-donating atoms.
