Abstract

A series of ruthenium(II) complexes with the pyrazolyl alkane ligands tris(1-pyrazolyl)methane 1 (TPM) and bis(1-pyrazolyl)methane 2 (BPM) have been synthesized and characterised. The complex [RuCl(PPh₃)₂(TPM)]⁺X (X = Cl 3a or BF₄ 3b) was formed by the reaction of TPM with RuCl₂(PPh₃)₃ and [Ru(CO)H(PPh₃)(TPM)]⁺X (X = Cl4a or BF₄ 4b) by the reaction of TPM with Ru(CO)ClH(PPh₃)₃. The complexes [RuCl (PPh₃)(BPM)₂]⁺Cl^- 5 and (BPM)(Ph₃P)Ru(μ-Cl)₃Ru(PPh₃)(BPM)] ⁺Cl^- 6 were synthesized by the reaction of BPM with RuCl₂(PPh₃)₃. Complexes 3-6 were characterised by multinuclear NMR spectroscopy, and 3a and 6 by X-ray crystallography. [RuCl(PPh₃)₂(TPM)]⁺Cl^- exhibits dynamic behaviour at low temperature and this is attributed to restricted rotation of the PPh₃ groups about the M-P bond.
