Article abstract of DOI:10.1039/DT9870002723

Improved procedures for the synthesis of the diruthenium(II)carboxylates, Ru2(μ-O2CR)4L2, and substitutions of either the bridged carboxylate or axial ligands (L) are described.Among new bridged compounds are the trifluoroacetate, Ru2(μ-O2CCF3)4, the carbonate, (Na3(Ru2(μ-O2CO)4)*6H2O)n, and the triazenide, Ru2(μ-N3Ph2)4; adducts of the triazenide include the nitrosyl, Ru2(μ-N3Ph2)4(NO)2, the isocyanide, Ru2(μ-N3Ph2)4(ButNC), and the carbonyl Ru2(μ-N3Ph2)4(CO)2.Reactions of the carboxylates with donors such as isocyanides, pyridine (py), phosphines, or CO leads in some cases to bridge cleavage and products such as trans- Ru(O2CR2)(py)4 or Ru(O2CR)2(PPh3)2 (R=Me or CF3), while the reactions with NO yield the diamagnetic adducts Ru2(μ-O2CR)4(NO)2.Infrared, n.m.r., e.s.r., and electronic spectra are recorded together with cyclic voltametric studies.The X-ray crystals structures of the dimers Ru2(μ-O2CCF3)4(thf)2 (thf=tetrahydrofuran) and Ru2(μ-O2CR4)(NO)2 (R=Et or CF3), and the polymer (Na3(Ru2(μ-O2CO)4)*6H2O)n are reported.
