A novel trigonal propeller-shaped hybrid tri-neodymium-polyoxometalate exhibiting single-molecule magnet behavior

A trigonal propeller-shaped hybrid polyoxometalate (POM) (NH2Me2)(3){[Nd(Mo4O13)(DMF)(4)](3)(BTC)(2)}center dot 8DMF (1; BTC = 1,3,5-benzenetricarboxylate) has been synthesized and structurally characterized. The planar {Mo-4} segment is tailored from the precursor Lindqvist polyoxoanion [Mo6O19](2-) firstly, and plays a key role in the reassembly of 1. Furthermore, the magnetic studies reveal that 1 shows single-molecule magnet (SMM) behavior.
