Bis(pyrazol-1-yl)acetato ligands in ruthenium chemistry: Syntheses and structures of ruthenium(II) and ruthenium(III) complexes with bpza and bdmpza
New ruthenium(II) and ruthenium(III) complexes with the ligands bis(pyrazol-1-yl) acetate (bpza) and bis(3,5-dimethylpyrazol-1-yl)acetate (bdmpza) are reported. The reaction of ruthenium trichloride hydrate, H[bpza], and excess PPh3 yielded [Ru
