A hexameric [MnIII18Na6] wheel based on [MnIII3O]7+ sub-units

A novel hexameric [MnIII18Na6] wheel-like aggregate consisting of [MnIII3O] triangles is reported. It is the second highest nuclearity oxime-based Mn cluster, the largest member of the recently-developed family of molecular oligomers based on [MnIII3O] triangles, and the only one with a wheel-like metal topology.
