The first metallo‐scorpionate ligands, closely related to Trofimenko's scorpionates, are obtained by formal replacement of the hydrido‐boron moiety of hydrido‐tris(pyrazolyl)borate by an (arene)Ru II fragment. Coordination to divalent and trivalent 3d‐transition metals (Fe, Co, Ni, Cu) gives access to a series of homoleptic, heterotrimetallic complexes containing linear metal chains bridged by pyrazole ligands. Synthetic aspects, spectroscopic, structural and electrochemical properties are reported and compared to those of standard scorpionate complexes.
