چکیده انگلیسی
The new zinc silico-phenylphosphonate has been synthesised. The substitution of phosphorus by silicon induced a deficit of the positive charges that were balanced by cations located in the interlayer space. The XRD pattern exhibits a series of (00l) reflections corresponding to a lamellar structure. The SEM micrograph of this material shows a morphology similar to the one observed for clay minerals and especially smectites “gypsum-like morphology”. TEM images exhibit a rods' arrangement for the layered materials. Q4 sites were identified by 29Si solid state NMR measurement indicating a full polymerisation of the silica.
