Abstract

Solid-state ⁷¹Ga and ⁶⁹Ga NMR was used to probe the structure of the hydroxo-aquo cluster, [Ga₁₃(μ₃-OH)₆(μ₂-OH)₁₈(H₂O)₂₄](NO₃)₁₅, envisioned as a solution-processable material for thin film electronics. This species, termed Ga₁₃, is made up of three types of 6-coordinate gallium sites, with bridging OH groups and H₂O species decorating the outer edges. Solid-state NMR at two magnetic fields (13.9 and 21.1 T) of these quadrupolar nuclei, in conjunction with modeling, demonstrates that these sites are best represented as distorted octahedra, exhibiting a wide range of distinct quadrupolar couplings and asymmetry parameters. This information is critical for analyses of the local coordination environment for gallium in related gallium-oxide films, and this work adds to the growing body of evidence that gallium solid-state NMR is a useful tool for structural analyses.
