Investigation of the structure of new gallium phosphonate based hybrid materials by P-31, Ga-71, and H-1 solid-state NMR

Modern high-resolution solid-state NMR is a powerful tool for probing the s tructure of phosphonate-based hybrid materials, in the organic as well as i n the inorganic region. This is illustrated in the case of a series of new gallium phosphonates [Ga(OH)(O3PCH3).x H2O [x = 1 (1); x = 0 (1')] and Ga(O H)(O3PCH2C6H5) (2)], that were characterized by X-ray diffraction and FTIR, and then studied using Ga-71, P-31, and H-1 NMR.
