Hydrothermal Assembly of a Novel Three-Dimensional Framework Formed by [GdMo12O42]9- Anions and Nine Coordinated GdIII Cations

The three-dimensional framework of [Gd(H2O)3]3[GdMo12O42]vdt·3H2O, 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 Sil...

Description
Summary:The three-dimensional framework of [Gd(H2O)3]3[GdMo12O42]vdt·3H2O, 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 GdIII atoms and linking up six other neighboring [Mo12GdO42]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.
