Before revision: The longest EMACs that have been constructed so far incorporate nine Ni atoms and have a length of approximately 2 nanometers, although it is estimated that chains with up to 17 metal atoms (4-5 nanometers) could be accessed with currently available ligands.
After revision: The longest EMACs that have been constructed so far incorporate eleven Ni atoms and have a length of approximately 2 nanometers, although it is estimated that chains with up to 17 metal atoms (4-5 nanometers) could be accessed with currently available ligands.
