Abstract
The synthesis and characterization of three novel heterobimetallic derivatives of general formula [RuClCp(PPh3)-μ-dmoPTA-1κP:2κ2N,N′-MCl2] (M = Co (1), Ni (2) and Zn (3), dmoPTA = 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) are described. The sizes of their diffusing units are in agreement with the solid-state structures of 2 and 3, supporting a similar solid-state structure for complex 1. The diamagnetic ruthenium–zinc derivative 3 was fully characterized in solution at 193 K by
