Novel [Ru(L)(Tpms)]Cl and [Ru(L)(TpmsPh)]Cl
complexes
(L = p-cymene, benzene, or hexamethylbenzene, Tpms
= tris(pyrazolyl)methanesulfonate, TpmsPh = tris(3-phenylpyrazolyl)methanesulfonate)
have been prepared by reaction of [Ru(L)(μ-Cl)2]2 with Li[Tpms] and Li[TpmsPh], respectively. [Ru(p-cymene)(Tpms)]BF4 has been synthesized through
a metathetic reaction of [Ru(p-cymene)(Tpms)]Cl with
AgBF4. [RuCl(cod)(Tpms)] (cod = 1,5-cyclooctadiene) and
[RuCl(cod)(TpmsPh)] are also reported, being obtained by
reaction of [RuCl2(cod)(MeCN)2] with Li[Tpms]
and Li[TpmsPh], respectively. The structures of the complexes
and the coordination modes of the ligands have been established by
IR, NMR, and single-crystal X-ray diffraction (for [RuL(Tpms)]X (L
= p-cymene or HMB, X = Cl; L = p-cymene, X = BF4)) studies. Electrochemical studies showed
that each complex undergoes a single-electron RuII →
RuIII oxidation at a potential measured by cyclic voltammetry,
allowing to compare the electron-donor characters of the tris(pyrazolyl)methanesulfonate
and arene ligands, and to estimate, for the first time, the values
of the Lever EL ligand parameter for TmpsPh, HMB, and cod.
