Magnetostructural correlation in isolated trinuclear iron(iii) oxo acetate complexes

We elucidate the correlation between geometric structures and magnetic couplings in trinuclear iron(iii) oxo acetate complexes[Fe3O(OAc)6(Py)n]+(n= 0, 1, 2, 3) when isolated and trapped as gaseous ions.

Magneto-structural correlation of hexakis-dmso cobalt(ii) complex

The magnetostructural correlation of the hexakis-dmso cobalt(ii) complex, [Co(dmso)6](BPh4)2 (dmso: dimethylsulfoxide), was investigated by single-crystal X-ray diffraction study and magnetic measurements.

Multinuclear Ni(ii), Cu(ii) and Zn(ii) complexes of chiral macrocyclic nonaazamine

Herein, we report the preparation and crystal structures of Ni(ii), Cu(ii) and Zn(ii) complexes. For both the Ni(ii) and Cu(ii) compounds, a magnetostructural correlation was established.

The new dicyanoruthenium(iii) building block with 2′-hydroxyacetophenone imine for heterobimetallic complexes

Five one-dimensional heterobimetallic chains based on the new dicyanoruthenium(iii) complex, trans-(Ph4P)[Ru(L)2(CN)2] (L = 2′-hydroxyacetophenone imine), are synthesized and structurally characterized. Magnetostructural correlation for these compounds is discussed.

Magnetostructural characterization of copper(II) hydroxide dimers and coordination polymers coordinated to apical isothiocyanate and cyanide-based counteranions

Five Cu(II) hydroxo-bridged complexes of the type [Cu2(μ-OH)2(L)2][A]x·yH2O (where L = 1,10-phenanthroline, A = NCS–, x = 2, y = 2 (1); L = 2,2′-bipyridine, A = NCS–, x = 2, y = 1 (2); L = 2,2′-bipyridine, A = [Au(CN)4]–, x = 2, y = 0 (3) and 2 (4); L = N,N,N′,N′-teteramethylethylenediamine, A = [Pt(SCN)4]2–, x = 1, y = 0 (5)) have been prepared and have been characterized by elemental analysis, IR and Raman spectroscopy, X-ray crystallography, and SQUID magnetometry. Complexes 1 and 2 consist of five-coordinate Cu(II) hydroxo-bridged dinuclear units bound to two NCS– anions in the apical positions, 3 and 4 are pseudo-polymorphs of a Cu(II) hydroxo-bridged dimer core with [Au(CN)4]– counteranions, and 5 is a coordination polymer of Cu(II) hydroxo-bridged dimers with trans-bridging [Pt(SCN)4]2– anions coordinated in the apical position of the five-coordinate Cu(II) centres. The magnetic susceptibility versus temperature for each system was measured, fit to obtain J-coupling values (which range from –0.37 to 17.8 cm−1), and qualitatively compared to known magnetostructural correlation parameters.
