Abstract

It was shown that refluxing of europium(III) acetate hydrate with trifluoroacetic acid in a dioxane–acetonitrile mixture gives the polymer {[Eu(μ-OOCCF₃)₃(OH₂)₂]}_n (I) containing dioxane solvate molecules. The reaction of I with [phen(µ-OOC^tBu)₂(OOC^tBu)₂] (II) (phen = 1,10-phenanthroline) in CH₂Cl₂ at room temperature gives a precipitate, the recrystallization of which from acetonitrile affords an unusual trinuclear heterometallic heteroanionic phen₂Zn₂Eu(µ³-OH)(OOC^tBu)₄(OOCCF₃)₂ complex (III). The structure of the products was established from X-ray diffraction data (CCDC no. 2235937–2235939). The optical properties of complex III were studied.
