Publication in Inorganic Chemistry

Publication entitled "Single-Chain Magnet Based on 1D Polymeric Azido-Bridged Seven-Coordinate Fe(II) Complex with a Pyridine-Based Macrocyclic Ligand" (authors: B. Drahoš, R. Herchel, Z. Trávníček) has been published in the chemistry journal Inorganic Chemistry. Peculiar magnetic behavior was described for 1D-polymeric seven-coordinate pentagonal bipyramidal Fe(II) complex {[Fe(L)(μ1,3-N3)](ClO4)}n with a pentadentate macrocyclic ligand L (3,12,18-triaza-6,9-dioxabicyclo[12.3.1]octadeca-1(18),14,16-triene) coordinated in the pentagonal equatorial plane and with end-to-end bridging azido ligands in axial positions. The static and dynamic magnetic data revealed that spin-canting in the 1D-chain of the complex results in the single-chain magnet (SCM) behavior with high spin-reversal energy barrier Ueff (Δτ) = 87.5 K, exhibiting magnetic hysteresis below 4 K and coexistence with the metamagnetism altogether resulting in weak 3D-ferromagnetic behavior. This is the first reported example of the exclusively azido-bridged homospin Fe(II)-based SCM.
