Abstract: 
Two ruthenium(II) 4-ethynylpyridine-hydride complexes bearing one Lewis-basic nitrogen atom as coordination site, namely trans-Ru(dppe)2H(C[triple bond, length as m-dash]Cpy-4) (1) and trans-Ru(dppm)2H(C[triple bond, length as m-dash]Cpy-4) (2) (dppe = 1,2-bis(diphenylphosphino) ethane, dppm = 1,2-bis(diphenylphosphino) methane) and Ru(dmpe)2(C[triple bond, length as m-dash]Cpy-4)2 (3) (dmpe = 1,2-bis(dimethylphosphino) ethane) with two nitrogen donor atoms were applied to synthesize the heterobimetallic mixed Ru/Re complexes 4–7. The X-ray crystal structure of the binuclear complex [Re(CO)3(t-bu2bipy)Ru(dppe)2(C[triple bond, length as m-dash]Cpy-4)H] [OS([double bond, length as m-dash]O)2CF3] (t-bu2bipy = 4, 4′-di (t-butyl)-2,2′-bipyridine, (7)) has been determined. Besides the usual characterization (IR, NMR, UV/Vis, EA) of the compounds 1–7, thermogravimmetry (TG) and cyclovoltammetry (CV) of selected complexes were measured in order to study the interaction between the organometallic building blocks. The existence of long-range RuRe interactions has been observed.
