摘要：

This paper describes the isolation of four layered double hydroxide (LDH) compounds having the general formula [(Ni3-xCrxIII)-Cr-II(OH)(6)](CO3)(x/2)center dot yH(2)O [x = 0.57 (1), 0.69 (2), 0.81 (3) and 0.93 (4)] by using homogeneous precipitation methods and varying the metal ratio in the synthetic solutions. All the reported compounds have carbonate anions in the interlamellar space. This fact forces the interlayer distances to remain unchanged in all the cases, thus providing an ideal system in which the changes observed in magnetic properties can be correlated with metal composition along the hydroxide layers.
