Description
Summary:The three-dimensional framework of [Gd(H(2)O)(3)](3)[GdMo(12)O(42)]vdt.3H(2)O, which was synthesized from hydrothermal reaction, is built up from Silverton-type anions linked by nine coordinated gadolinium(III) cations. It is the first time that the paramagnetic lanthanide(III) cation is introduced into the Silverton-type anionic center in the heteropolymolybdate chemistry, and it acts as 18 dentate ligands coordinating to six Gd(III) atoms and linking up six other neighboring [Mo(12)GdO(42)](9-) units in a staggered manner to generate a remarkable three-dimensional framework. The magnetic susceptibility measurement suggests that the weak antiferromagnetic behavior results from the transformation of O-Mo-O units, which has been confirmed by EPR spectra.
