- 9Reactions were monitored by electrospray mass spectrometry in all cases and by 1H NMR spectroscopy for systems not containing paramagnetic metals.
- 10The L1 and L2 resonances in [Zn(L1L2)](ClO4)2] were distinguished by a combination of COSY and ROESY experiments.

The structure was solved by direct methods and refined by full-matrix least-squares on F2 values of all data (G. M. Sheldrick, SHELXTL manual, Siemens Analytical X-ray Instruments, Madison WI, USA, 1994, version 5) to give wR={∑[w(F
−F
)2]/∑[w(F
)2]}1/2=0.1536, conventional R=0.0627 for F values of 22989 reflections with F
>2σF
), S=1.048 for 1371 parameters. Residual electron density extremes were 1.12 and −0.89 e Å−3. Hydrogens were added in calculated positions and constrained to a Riding model.

- 12Under identical experimental conditions the reduced thread, H4L2, does not afford [Zn(L1H4L2)](ClO4)2, thus precluding the possibility of a “slippage” mechanism.

The greater stability of octahedral metal–imine complexes, compared with metal–amine complexes, is also illustrated by the facile demetallation of amine—but not imine—octahedral metal catenates.[7]
