چکیده
In the title binuclear iron(III) complex, [Fe(2)(C(14)H(10)N(2)O(2))(3)]·4C(4)H(8)O or [Fe(2)(salda)(3)]·4THF [H(2)salda = 2,2'-(azinidimethyl-ene)diphenolate and THF is tetra-hydro-furan], 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 C(2) symmetry, the rotation axis bis-ecting one N-N bond.

The title compound, [Al2K2(C2H6N)8(C4H8O)] n , formed during the sonochemical reaction between Al(NMe2)3 and sodium-potassium alloy in the presence of tetra-hydro-furan (THF). Its asymmetric unit has two inequivalent K(+) sites. One site is coordinated by a THF ligand, and crystallizes as a one-dimensional polymer with a backbone of catenated AlN2K rings. A twofold rotation axis bis-ects one K(...
متن کاملEvaluating the identity and diiron core transformations of a (μ-oxo)diiron(III) complex supported by electron-rich tris(pyridyl-2-methyl)amine ligands.
The composition of a (μ-oxo)diiron(III) complex coordinated by tris[(3,5-dimethyl-4-methoxy)pyridyl-2-methyl]amine (R(3)TPA) ligands was investigated. Characterization using a variety of spectroscopic methods and X-ray crystallography indicated that the reaction of iron(III) perchlorate, sodium hydroxide, and R(3)TPA affords [Fe(2)(μ-O)(μ-OH)(R(3)TPA)(2)](ClO(4))(3) (2) rather than the previous...

The title ion-association metal complex, [Li(C4H8O)4]2[Mg2(C43H61O3)2], has been synthesized from the tridentate phenolic ligand tris-(3,5-di-tert-butyl-2-hy-droxy-phen-yl)methane in tetra-hydro-furan (THF). The aryl-oxo magnesiate complex anion is binuclear with each Mg2O4 complex unit inversion-related and bridged through the two tridentate chelating phenolate O-donors of the ligand. The comp...
