Encapsulating beryllium – Synthesis, characterisation and modelling of a chiral binaphthyldiimine-Be(II) complex

Beryllium has been successfully incorporated into a naphthalene containing Schiff base ligand. Evidence from 9Be and 1H NMR data and model compounds indicate that the ligand completely encapsulates the beryllium cation via tetra-dentate tetrahedral coordination using both phenol and imine donors. Calculated 9Be NMR data at the B3LYP/6-311G+(2d,p) DFT level of theory is in agreement with this conclusion.
