Long‐Range Magnetic Ordering in a Tb^III–Mo^V Cyanido‐Bridged Quasi‐One‐Dimensional Complex

Abstract

One-dimensional polymer [Tb(pzam)3(H2O)Mo(CN)8]⋅H2O (see picture, pzam=pyrazine-2-carboxamide; C black, Mo yellow, N blue, O red, Tb green) has been synthesized and characterized. Its magnetic susceptibility data indicate substantial ferromagnetic superexchange between TbIII and MoV via the cyanido bridge, and the occurrence of long-range magnetic ordering between chains at Tc≈1 K.
