For both GaLA and GaBA, when the distance between Ga and the neutral donor (RGa-O) is increased above 0.25 Å longer than the ground state structure (i.e. RGa-O > 2.3 Å), a rapid convergence towards CQ expected for a tri-coordinate Ga site (61 MHz) is observed. Collectively these data illustrate that δiso and CQ values for neutral, tetra-coordinate Ga sites consisting of 3 anionic siloxy ligands and an adjacent neutral donor, depend heavily on the RGa-O; and in the absence of exogenous probe molecules the NMR parameters make the two types of site (GaLA and GaBA) challenging to distinguish by 71 Ga NMR spectroscopy alone.
