Abstract

Obtaining three-dimensional (3D) configurational information of surface organometallic complexes is a persistent challenge due to the low spatial sensitivity of most spectroscopic methods. We show that employing ¹⁷O-enriched supports enables highly informative multidimensional NMR experiments, including radial and vertical distance measurements, that can be used to elucidate site geometry.
