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 BF43b) was formed by the reaction of TPM with RuCl2(PPh3)3 and [Ru(CO)H(PPh3)(TPM)]+X (X = Cl 4a or BF44b) 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.
