Donor/acceptor complexes containing ferrocenyl-pyridine ligands attached to a tungsten carbonyl centre: Structural, spectroscopic and electrochemical properties

Abstract The NQR frequencies of the 63,65 Cu nuclei in di-coordinated complex cations of Cu 1 , having the general formula CuL 2X, where L is a substituted pyridine and X is a hard anion such as ClO4 , are reported and discussed in the light of the known crystal structures. A departure from a strictly linear geometry of the L 2 Cu cation has but little effect on the resonance frequency, but the donor-acceptor bond between the nitrate anion and the copper atom in bis(2,6-lutidine)cuprous nitrate, which was postulated on crystallographic grounds, is confirmed by the NQR results, which also indicate a similar interaction in bis(2,6-lutidine)cuprous trifluoroacetate. A number of the complexes discussed here have not been reported previously.

Treatment of Ru(acac)3 with 2-cyano-pyridine and 3,5-dimethyl-pyridine in the presence of zinc dust as reducing agent in refluxing THF afforded the ruthenium(II) complexes cis-[RuII(acac)2(2- CN-py)2] (1) and cis-[RuII(acac)2(3,5-Me2-py)2] (2), respectively. Interaction of Ru(acac)3 with 3- Me-pyridine and 3,5-Me2-pyridine in the presence of Br2 in refluxing THF gave the ruthenium(III) complexes [RuIII(acac)Br2(3-Me-py)2] (3) and [RuIII(acac)Br2(3,5-Me2-py)2] (4), respectively. The four complexes have been spectroscopically and electrochemically characterized, and their crystal and molecular structures have been established by X-ray crystallography
