Synthesis, structure, and magnetic properties of a large lanthanide-transition-metal single-molecule magnet

Abstract

The largest known Dy-Mn complex is [DyIII6Mn III4MnIV2(H2shi) 4(Hshi)2(Shi)10] (H3shi is salicylhydroxamic acid; see stereopicture). The Dy ions are arranged in a nearly planar hexagonal ring and are capped on opposite sides by a Mn III2MnIV trimer. This mixed-metal topology provides a new structure class for the examination of interesting magnetic phenomena of individual molecules.
