The octanuclear europium cluster [bmpyr]6[Eu8(μ 4-O)(μ3-OH)12(μ2-OTf) 14(μ1-Tf)2](HOTf)1.5 obtained from the ionic liquid [bmpyr][OTf]

The octanuclear europium cluster compound [bmpyr]6[Eu 8(μ4-O)(μ3-OH)12(μ 2-OTf)14(μ1-OTf)2](HOTf) 1.5 has been crystallized from the ionic liquid [bmpyr][OTf]. Structural characterization by single crystal X-ray diffraction revealed an Bug cluster unit which is centered by an oxide anion. The Bug-cluster polyhedron can be described as a bicapped octahedron or a triangulated dodecahedron. Each of the triangular faces of the cluster is capped by one μ3-hydroxo group. Fourteen μ2-triflate (CF3SO3 -) anions bridge via oxygen the cluster edges. Together with two μ1-terminal coordinating triflate anions they complete the cluster unit. Six cations from the ionic liquid counterbalance the cluster charge. Additionally, 1.5 HOTf molecules per Bug-cluster unit are incorporated in the crystal structure of the title compound.

Metal ion-catalyzed Diels-Alder and hydride transfer reactions. Catalysis of metal ions in the electron-transfer step

Rates of Diels - Alder cycloaddition of anthracenes with p-benzoquinone and its derivatives as well as rates of hydride-transfer reactions from 10-methyl-9,10-dihydroacridine to the same series of p-benzoquinones are accelerated significantly in the presence of metal ions in acetonitrile. An extensive comparison of the catalytic effects of metal ions in electron transfer from one-electron reductants (cobalt tetraphenylporphyrin and decamethyrferrocene) to p-benzoquinones with those in the Diels - Alder reactions of the quinones as well as the hydride-transfer reactions has revealed that the catalysis of metal ions in each case is ascribed to the 1:1 and 1:2 complexes formed between the corresponding semiquinone radical anions and metal ions. The transient absorption and ESR spectra of the semiquinone radical anion-metal ion complexes are detected directly in the electron-transfer reduction of p-benzoquinone derivatives in the presence of metal ions. The catalytic reactivities of a variety of metal ions in each reaction are well correlated with the energy splitting values of πg levels because of the complex formation between O2.- andMn+, which are derived from the gzz values of the ESR spectra of the O2.--Mn+ complex.
