Abstract

The structures of three adventitiously obtained peroxolanthanoid complexes have been determined, namely, [Yb-2(Cp)(4)(mu-O)(2/3)(mu-O-2)(1/3)(thf)(2)] (1) (Cp = cyclopentadienyl; thf = tetrahydrauran), which has disorder between the bridging oxide and peroxide, [Nd-2(o-PhPhForm)(4)(thf)(4)(mu-O-2)] (2) (o-PhPhForm = N,N'-bis(2-phenylphenyl)formamidinate), and [Eu-4(FForm)(6)(mu-OH)(2)(mu(3)-O-2)(2)(mu-diglyme)(2)]center dot 2diglyme (3) (FForm = N,N'-bis(2-fluorophenyl)formamidinate, diglyme = bis (2-methoxyethyl) ether). In the first two complexes, the peroxide bridges side-on between metals, whereas in the last complex, each peroxide bridges three metals through both oxygen atoms. The first complex was a single crystal amongst a bulk sample of [Yb(Cp)(2)(pzPh)(thf)] (pzPh = 2-(1'-pyrazolyl)phenyl), prepared by oxidation of dicyclopentadienylyt-terbium(II) by bis(2-(1'-pyrazolyl)phenyl)mercury, the structure of which was also determined and showed distorted square planar stereochemistry for mercury.
