Heterometallic chiral [Mn13Cu8] single-molecule magnets

An enantiomeric pair of 3d-3d heterometallic clusters of {(MnMe12Cu8II)-Me-II-Cu-III) has been synthesized in an aqueous solution without heating. The crystal structures reveal a five-layered core of {(MnMe12Cu8II)-Me-II-Cu-III}, which is a slightly distorted {(MnMn12III)-Mn-II) tetradecahedron with its eight triangular faces capped by a Cu-II ion respectively. The magnetic measurement results establish that anisotropic Mn-III atom-containing clusters L-1 and D-1 exhibit slow relaxation of their magnetization vectors.

Automated summary

This article describes the synthesis of an enantiomeric pair of 3d-3d heterometallic clusters in an aqueous solution without heating. The crystal structures reveal a five-layered core structure with a slightly distorted tetradecahedron composed of Mn and Cu ions. Magnetic measurements show that these clusters exhibit slow relaxation of their magnetization vectors.
