Synthetic transition metal phyllosilicates and organic-inorganic related phases

Abstract

We present a brief overview of the first-row transition metal phyllosilicates and their organically functionalised analogues obtained under autogenous pressure conditions. Some structural features of phyllosilicates are first recalled and the magnetic properties of Co²⁺ and Ni²⁺ phyllosilicates are described. In the second part, the state-of-the-art in organically functionalised phyllosilicates is reported, including our contributions on the structural and magnetic characterisation. The impetus is to enhance the potential of these new compounds as multi-property materials. Since our interest lies in low-dimensional magnetic properties, divalent transition metal cations are involved in the layered inorganic layers, whereas 3-aminopropyltriethoxysilane is used as the silicon source.
