    • The initial structure was built based on the X ray structure (1 R=Ph) and put into thorough conformational survey by rotation of the bonds using MM2 and optimized by MM2 and PM3 (precise) on the Cache system. Since both calculations gave the almost same structures and stability relationships, the MM2 structures and energies were presented.

    • The rough calculations (MM2) of metal coordinated imide indicate stability of the chelated syn-1- metal complex more than anti-1 metal coordinated complex.

    • Molecular orbital calculations by PM3 indicate that LUMO energy of the metal-coordinated imide is significantly lower than that of the metal non-coordinated species.
