Synthesis and characterisation of ruthenium(II) arene complexes containing κ3- and κ2-poly(pyrazolyl)borates and methanes

Synthesis, Crystal Structures and Redox Properties of Mixed‐Sandwich Complexes of Ruthenium(II) with Cyclopentadienyl and Tris(pyrazolyl)methane Ligands

“…A comparable structural motif has been found, for instance, in the ruthenium(II) arene complex [Ru(C 6 H 6 )(κ 2 N-Me Tpm)Cl][PF 6 ]. [15] Due to steric crowding in 4, the separation between the Cp cent and the ruthenium atom (180.4 pm) is slightly longer than those found for 1 or 2 (176.4 and 178.2 pm, respectively). This is also apparent from the elongated Ru-N pz distances [av.…”

Preparation, characterization, and catalytic properties of ruthenium nitrosyl complexes with polypyrazolylmethane ligands

“…Polypyrazolylmethanes, such as bis(3,5-dimethyl-1-pyrazolylmethane) (Bpm * ) and tris(1-pyrazolyl)methane (Tpm), are the neutral analogues of the Bp and Tp ligands [36,37], which are isosteric and isoelectronic with the anionic polypyrazolyborates. Ruthenium complexes with Bpm and Tpm and their derivatives have also been prepared [38][39][40][41][42][43]. However ruthenium nitrosyl complexes of polypyrazolylmethanes are scarcely studied.…”

New RuII(arene) Complexes with Halogen‐Substituted Bis‐ and Tris(pyrazol‐1‐yl)borate Ligands

“…[1,2] Their metal-complex applications range from enzyme mimics [3] to catalysts in a variety of reactions. [4] Recent interest has arisen in the use of scorpionates in association with Ru II (arene) acceptors, [5] which are known for their flexibility in permitting variation of the steric hindrance of the arene and electronic features of the amphiphilic organometallic moiety. These structural variables provide "handles" for catalysis, [6] supramolecular assemblies, and molecular devices, [7] whereas the piano stool h 6 -arene ruthenium complexes have shown antiviral, antibiotic, and anticancer activities.…”
