    • Geometry optimisations and harmonic vibrational frequency calculations were performed using the ab-initio Hartree-Fock (HF) method and the B3LYP density functional in the Gaussian '03 suite of programs.[16] The harmonic vibrational frequency calculations were performed to ensure that the optimised structures were indeed true minima (0 imaginary frequencies, All atoms were treated with the split-valence double-zeta 6-31 g Pople-type basis set. Calculations involving the addition of diffuse and polarisation functions to this basis set were also performed on the E and Z-Isomers of compound [Na1, but were found to yield very similar results to the 6-31 g basis set. Due to this and the large increase in calculation time upon the addition of these functions to the basis set, further calculations were performed with the standard 6-31 g basis set
