Yttrium(III) and lanthanide(III) vanadates corresponding to the general formula AVO 4 (A = Y, Pr, Sm, Eu, Gd, Dy, Er) were prepared by a nonconventional soft chemistry route in which coordination compounds of the different elements to be incorporated were used as molecular precursors. In this case, EDTA-based yttrium(III), lanthanide(III) and vanadium(V) complexes were synthesised, characterised and used as precursors for the preparation of zircon-type AVO 4 materi-
