SYNTHESIS, CRYSTAL STRUCTURE AND MAGNETIC BEHAVIOUR OF NOVEL 4f-2s HETEROMETALIC ONE-DIMENSIONAL COORDINATION POLYMERS ON THE BASE OF 2-FURAN-CARBOXYLIC ACID

Abstract

Nine new complexes with the general formula {[Ln2Ba(α-Fur)8(H2O)4]}n, where Ln = Nd3+, Sm3+, Eu3+, Pr3+, Gd3+, Tb3+, Ho3+, Er3+ and La3+; α-Fur ≡ C4H3OCOO, were synthesized and characterized by IR spectra, magnetism, X-ray single crystal and powder diffractions.
