From oxo to carbonyl and arene complexes; A journey through technetium chemistry

Starting from [99TcO4]− or [99Tc2O7], many fundamental organometallic technetium complexes become accessible under ambient conditions. This lead to a fruitful interplay between fundamental and applied bioorganometallic 99mTc chemistry, initiated by the search for [Cp*99TcO3], an elusive compound until to date.163
