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-OOCtBu)2(OOCtBu)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)(OOCtBu)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.
