Tris[-2,2'-(azinodimethylidyne)diphenolato-⁴O,N:N',O']diiron(III) tetrahydrofuran tetrasolvate

J. Wang, B. Liu and B. Yang

Abstract: In the title binuclear iron(III) complex, [Fe₂(C₁₄H₁₀N₂O₂)₃]·4C₄H₈O or [Fe₂(salda)₃]·4THF [H₂salda = 2,2'-(azinidimethylene)diphenolate and THF is tetrahydrofuran], the ligand possesses a rotationally flexible single N-N bond. Three dinucleating O,N:N',O'-donor ligands provide three diazine (=N-N=) bridges between the metal ions, yielding a binuclear triple helicate structure with crystallographic C₂ symmetry, the rotation axis bisecting one N-N bond.
