Visualization of Weak Interaction Effects on N<sub>2</sub>O Schiff Base Ligands in Iron(II) Spin Crossover Complexes

چکیده
Single crystals of an iron(II) spin crossover (SCO) complex containing N2O Schiff base ligand, [FeII(qsal-COOH)2], were successfully prepared. The crystal structures from a single-crystal X-ray diffraction study obtained at 100 and 170 K yielded information regarding both the low-spin high-spin states, without any breakage being observed after phase transition. Structural analysis was performed to visualize origin SCO phenomenon in [FeII(qsal-COOH)2] complex. We report that fundamental requirements for abrupt SCO, particularly Fe-qsal complexes, are not only combination weak interaction effects, such as π–π, P4AE (parallel four-fold aryl embrace), hydrogen bonding, but also presence solvents crystalline structure, since solvent molecules can influence interactions between [FeII(qsal-X)2] molecules.

Iron(II) spin crossover complexes with diaminonaphthalene-based Schiff base-like ligands: mononuclear complexes.
The synthesis of new Schiff base-like ligands with extended π-system and their iron complexes is described. Some of the iron(ii) complexes with N-heterocycles as axial ligands show spin crossover behaviour. The influence of the extended aromatic system on cooperative interactions is investigated by single crystal X-ray structure analysis, X-ray powder diffraction, and magnetic measurements. A c...
متن کاملBidentate Isatin Schiff Base Ligands Oxovanadium (IV) Complexes
The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
