Abstract:	The syntheses and full characterization of novel ruthenium complexes based on 1,3-dicyanobenzene are described. Crystal structures are reported for both 1,3-(cis-RuCl(P(CH₃)₃)₄NC)₂C₆H₄]PF₆]₂ (1cis) and 1,3-(trans-RuCl(dppe)₂NC)₂C₆H₄]H₂PO₄]₂ (3′). Ligand substitution in the homobimetallic complex (3) leads easily to the monometallic analogue, 1,3-(trans-RuCl(dppe)₂NC)C₆H₄(CN)]PF₆] (4). A heterobimetallic complex, 1,3-(trans-RuCl(dppe)₂NC)C₆H₄(CN-FeCp(dppe))]PF₆]₂ (5), of satisfactory purity is also obtained.

Keywords:	Nitrile Ruthenium Ligand substitution Homobimetallic Heterobimetallic Building block
