Heterometallic lanthanide-centred [Ni II6LnIII] rings†
Abstract
A [NiII6DyIII] heptanuclear complex featuring a rare six-membered {NiII6} metal ring surrounding the central Dy(III) ion is reported. Magnetic studies reveal single-molecule magnet behaviour for the complex under zero external dc field, while replacing the DyIII ion with ϒIII or GdIII ions allows for a comprehensive understanding of the magnetic behaviour.
