MagSaki software was developed for the magnetic analysis of dinuclear high-spin cobalt(II) complexes. This software performs magnetic analysis to determine magnetic parameters using several types of theoretical calculations, such as the following: (1) a mononuclear complex in an isotropic octahedral field, (2) a mononuclear complex in an axially distorted octahedral field, (3) a dinuclear compl...

A new synthetic procedure for the efficient preparation of dinuclear ruthenium(II) polypyridyl complexes is reported. The compounds synthesized are [(bpy)2Ru(BPBT)Ru(bpy)2](PF6)2 and [(bpy)2Ru(BPZBT)Ru(bpy)2](PF6)2. (bpy = 2,2’bipyridine; H2BPBT = 5,5’-bis(pyridin-2-yl)-3,3’-bis(1,2,4-triazole); H2BPZBT = 5,5’bis(pyrazin-2-yl)-3,3’-bis(1,2,4-triazole). Electrochemical experiments show that the ...

our main objective is a better understanding of spin spin interaction of dinuclear copper(ii) complexes through  system. the synthesis and characterization of two new dinuclear copper(ii) complexes, based on the use of large, pyrole-containing macrocycles, the so called “ expanded porphyrins” , [cu2(macrocycle)]4+ is described. a chloroform solution spectrum of two complexes taken at room tem...

the synthesis, spectroscopic and magnetic characterization of a series of new alkoxo-bridged binuclear copper (ii) compounds are described. all complexes have the general formula [cu (m-or)(l)2]2(clo4)2 · x h2o, in which m-or = ch3o-, c2h5o- or c3h7o-, l = 2-amino-4-methylpyridine (abbreviated a4pic) and 2-amino-5-methylpyridine ( abbreviated a5pic). the title compounds all consist of dinuclear...

We describe a ligand system that forms either a dinuclear double helicate or a dinuclear double mesocate dependent upon the size of the metal ion or the steric bulk of the ligand strand.

The SMM behaviour of dinuclear Ln(III)-Pc multiple-decker complexes (Ln = Tb(3+) and Dy(3+)) with energy barriers and slow-relaxation behaviour were explained by using X-ray crystallography and static and dynamic susceptibility measurements. In particular, interactions among the 4f electrons of several dinuclear Ln(III)-Pc type SMMs have never been discussed on the basis of the crystal structur...

Dinuclear structure of platinum( ii ) complexes favours thermally activated delayed fluorescence (TADF).

The R2 dimer of mouse ribonucleotide reductase contains a dinuclear iron-oxygen cluster and tyrosyl radical/subunit. The dinuclear diferrous form reacts with dioxygen to generate the tyrosyl radical essential for the catalytic reaction that occurs at the R1 dimer. It is important to understand how the reactivity toward oxygen is related to the crystal structure of the dinuclear cluster. For the...

The crystal structure of the dinuclear arene ruthenium title complex, [Ru2(C6H5OS)(C7H7S)2(C10H14)2]BF4, shows the two Ru(II) atoms to be bridged by two benzyl-thio-pheno-late units and one 4-hy-droxy-thio-pheno-late unit, with the remaining three coordination sites of each Ru(II) atom being occupied by p-cymene ligands, completing the typical piano-stool coordination geometry. The BF4 (-) coun...
