First mononuclear 1,3,4-oxadiazole based multifunctional Fe(II) complex (C1) and its Zn(II) analogue (C2) are reported. C1 shows SCO both in solid state and in solution at 207 K and 357 K respectively. Its SCO-luminescence interplay is investigated.
The influence of dopant molecules on the structure and functionality of spin-crossover materials is surveyed.
Spin-crossover metal–organic cages (SCO-MOCs), as stimulus-responsive molecular switches, integrate spin-state bistability with host–guest chemistry and tuneable architectures, offering promising applications as smart materials.
Four FeIII complexes of the Hqnal-5-Brq ligand have been characterized, marking them as the first examples of FeIII SCO complexes with a quinoline-substituted Hqnal ligand. The effects of anions and solvents on their SCO properties were assessed.
A unique 3D Hofmann-type framework containing [MoIII(CN)7]4− unit and FeII ion was synthesized and characterized. This compound exhibits an abrupt and hysteretic one-step SCO as well as ferrimagnetic ordering below about 65 K.
