Hydrolysis/Polycondensation in the Solid State: Access to Crystalline Silica-Based Hybrid Materials The authors are grateful to Dr. C. Dumas from the LBS laboratory at the Université de Montpellier I for the two-dimensional X-ray analysis.

Mild solid/gas or solid/liquid reactions can be used to prepare crystalline organosilicates, a class of silica-based hybrid materials, from the corresponding solid chlorosilanes. Hydrolysis and polycondensation in the solid state lead to the formation of the highly anisotropic organosilicates.
