Crystal structure and mössbauer spectroscopy studies of the ferrimagnetic complex bimetallic salt hexaamminechromium (III) hexachloroferrate (III), [Cr(NH3)6][FeCl6]
The crystal and molecular structures of the ferrimagnetic bimetallic complex salt hexaamminechromium(III) hexachloroferrate(III), [Cr(NH3)6][FeCl6], have been determined from single-crystal, three-dimensional x-ray diffraction counter data. The compound crystallizes as orange coloured crystals in the space groupC2/c of the monoclinic system with Z=4 and has cell dimensionsa=11.325(1) A,b=11.387(1) A,c=11.233(1) A, and β=90.83(1)A. The structure was refined by using segmented block diagonal least-squares techniques to discrepancy indices R and Rw of 0.0233 and 0.0285, respectively. The metal ions occupy sites with symmetry $$\bar 1$$ and are nearly octahedrally coordinated. In the [FeCl6]3− …
Alternating Chain Magnetism in Catena-μ-Oxo-Hemiporphyrazinatoiron(IV), The First μ-Oxo Linear Chain Complex Of Iron
Abstract X-ray studies, Mossbauer, and magnetism show FeOHp to be an antiferromagneticaly coupled alternating chain with J = -133 cm−1, g = 2.3 and an alternation parameter of 0.4.
