文摘Two novel hexacoordinated Co(II)-based single-ion magnets were prepared and characterised.Both neutral complexes feature metal-centred coordination with one terminal and one bidentate nitrate anions along with tridentate derivatives of a 2,6-bis(1H-benzimidazole-2-yl)pyridine ligand containing either n-octyl(complex 1)or n-dodecyl(complex 2)chains.The presence of long aliphatic chains ensures their solubility in low polarity and volatile solvents frequently used for lithography patterning.This enabled the preparation of microstructural layers and patterns on technologically relevant substrates by easy-tohandle and low-cost wet lithographic techniques.On the other hand,attempts at surface deposition via sublimation were not successful due to thermal instability.
