1D iron(ii)-1,2,4-triazolic chains with spin crossover assembled from discrete trinuclear complexes. Shylin, S. I., Shova, S., Shepherd, H. J., Ksenofontov, V., Tremel, W., & Gural'Skiy, I. A. Dalton Transactions, 51:2364-2369, Royal Society of Chemistry, 2, 2022.

We report on a molecular cationic iron(ii) complex with a 4-amino-1,2,4-triazole ligand and a tetraiodomercurate anion exhibiting an incomplete spin crossover (SCO). The complex exhibits an unusual disordered structure with a linear arrangement of ligand and water molecules that can potentially accommodate up to four iron atoms, but both terminal metal positions have half chemical occupancies, while occupancies of all ligands are full. This corresponds to the crystallisation of disordered trinuclear complexes arranged into 1D supramolecular chains. Iron cations have different N6 or N3O3 coordination environments, leading to the thermally induced SCO in two thirds of the metal centres. This SCO behaviour was characterised by magnetic susceptibility measurements and Mössbauer spectroscopy. This journal is
