The synthesis and characterization of three new ruthenium(II) carbonyl complexes with a bistriazole-2-ylidene (bitz) ligand are reported. These complexes have been fully characterized by elemental analyses, infrared, and 1H and 13C NMR spectroscopies. Their molecular structures were determined by single-crystal X-ray diffraction. The ruthenium(II) ion is in a distorted octahedral environment, in which the donor atoms are provided by two carbene carbon atoms of the bitz ligands, two carbonyl groups, and two halides. All compounds exhibit the cis(CO)-trans(halogen) conformation. The bite angles of these three complexes, 77.58(12)°, 77.13(14)° and 77.14(11)°, are small as a consequence of the chelation of the bitz ligands.
Graphical abstractThree ruthenium(II) carbonyl complexes with a bistriazole-2-ylidene (bitz) ligand have been prepared and characterized. The molecular structures were determined by single-crystal X-ray diffraction, which exhibit the six-coordinate distorted octahedral geometry with two carbene carbon atoms, two carbonyl groups, and two halide atoms. The bite angles, 77.58(12)°, 77.13(14)° and 77.14(11)°, are small as a consequence of the chelation of the bitz ligands.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Three ruthenium(II) complexes containing the bistriazole-2-ylidene ligand were prepared. ► Crystal structures for these complexes were determined by X-ray diffraction analysis. ► These complexes exhibit a distorted octahedral geometry around the Ru atom.
