摘要：

Lamellar organic-inorganic nickel silicates have been synthesised under hydrothermal conditions at 170 degreesC from a mixture of nickel acetate solution and (aminopropyl) triethoxysilane. The influence of the presence or absence of a mineralising agent such as HF or NH4F has been studied. Structural characterisations show that this material adopts a lamellar arrangement of nickel hydroxide layers separated by 21 Angstrom with, in the interspace, organically modified silicate entities linked to the inorganic layer. The hysteresis cycle and ac susceptibility have been carried out and reveal a paramagnetic-ferromagnetic transition below 20 K.
