Description	Non-hydrolytic condensation reactions became a powerful substitute for aqueous techniques in the area of sol-gel synthesis of multimetallic oxides and inorganic-organic hybrid materials in the form of xerogels, nanoparticles, and thin films. We developed a non-hydrolytic sol-gel route based on acetic acid ester elimination providing phosphosilicate hybrid inorganic-organic materials. The polycondensation reactions between Si(OAc)4 and OP(OSiMe3)3 led to microporous phosphosilicate xerogels with surface areas up to 568 m2 g-1. The consecutive substitution of Si and P precursors by acetoxysilanes 1RxSi(OC(O)CH3)4-x (1R = Me, Ph; x = 1-2) and trimethylsilylesters of phosphonic acid 2RP(O)(OSiMe3)2 (2R = c-Hex, Ph) caused the decrease of surface areas and increase of average pore sizes because of the lower cross-linking ability of the substituted precursors.
