摘要：

A new metavanadate inserted layered double hydroxide was prepared by a 'chimie douce' method. This material was characterized by X-ray diffraction, infrared spectroscopy, chemical analysis and thermogravimetry. Its structure consists of a packing of Ni0.70Co0.30(OH)(2) slabs, with (VO3)(n)(n-) metavanadate anionic chains intercalated within the interslab space. The influence of such chains on both the structural features and the exchange properties of the material was investigated. Heating this material to 190 degrees C leads to a grafting of the VO4 tetrahedra to the slabs coupled with a partial chain fragmentation.
