Syntheses and characterization of novel ruthenium complexes based on 1,3-dicyanobenzene

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)4Ntriple bond; length of mdashC)2C6H4][PF6]2 (1cis) and [1,3-(trans-RuCl(dppe)2Ntriple bond; length of mdashC)2C6H4][H2PO4]2 (3′). Ligand substitution in the homobimetallic complex (3) leads easily to the monometallic analogue, [1,3-(trans-RuCl(dppe)2Ntriple bond; length of mdashC)C6H4(Ctriple bond; length of mdashN)][PF6] (4). A heterobimetallic complex, [1,3-(trans-RuCl(dppe)2Ntriple bond; length of mdashC)C6H4(Ctriple bond; length of mdashN–FeCp(dppe))][PF6]2 (5), of satisfactory purity is also obtained.
