Na2Mn III6LnIII clusters with a non-equivalent core: chiral vs. meso isomerism†
Abstract
A wide family of clusters with the Na2MnIII6LnIII core derived from an enantiomerically pure or a racemic mixture of Schiff bases lead to the characterization of a unique case of chiral/meso isomers with C3/D3d symmetry respectively, involving the rearrangement of the cluster bond parameters and the change from hepta- to hexacoordination of the central LnIII cation.
