Abstract

23Na double-rotation NMR (DOR) provides details on site specific adsorption and anchoring interactions in intrazeolite hexacarbonylmetal(0) complexes, m{M(CO)6}-Na56Y, where M = Mo and W, and their molecular photooxidation products, n{MO3-x}-Na56Y, over the full composition range 0 < m ≤ 16, 0 < n ≤ 32 and 0 ≤ x ≤ 1. The shifts, intensities, and line shapes of the 23Na DOR resonances carry information on the environments of the extraframework Na+ binding sites within the zeolite lattice, as well as structural aspects of the guest species.
