Creation of a Tetranuclear MnIII2MnII2 Metalloring Structure Supported by a Penicillamine

The reaction of a Schiff-base ligand derived from 5-chloro-salicylaldehyde and D-penicillamine with MnIII ions in the presence of nBu3N produced a disulfide-bridged tetranuclear MnIII2MnII2 metalloring structure through thiolate oxidation. The corresponding treatment using Et3N instead of nBu3N gave a giant 13-nuclear MnIII6MnII7 structure.

Automated summary

The reaction of a Schiff-base ligand derived from 5-chloro-salicylaldehyde and D-penicillamine with MnIII ions in the presence of nBu3N or Et3N produced different metalloring structures, including a disulfide-bridged tetranuclear MnIII2MnII2 structure and a giant 13-nuclear MnIII6MnII7 structure.
