Octanuclear ferric complexes involving achiral phenolates of the general formula [Fe8(μ-O)4(μ-pz)12(R-C6H4O)4], (R = 4-NO2, 4-CN, 4-F, 4-Cl, 4-I, 4-CH3O, and 3-NO3), where synthesized and characterized by single crystal X-ray crystallography, elemental analysis, 1H-NMR, UV-Vis, IR, 57Fe Mössbauer spectroscopy and electrochemical methods (cyclic and differential pulse voltammetry). Results indicate that the nature of the phenolate substituents allows the fine tuning of the spectroscopic data of the compounds.
Subsequently, this project focused on the resolution of the racemic …

The main objective of this project is to synthesize the first family of polynuclear chromium pyrazolate complexes. Complexity in analysis of the experimental magnetic data of multinuclear complexes arises from their (2S +1)N microstates, where S is the spin of each metal center and N is the number of metal centers. For example, high-spin (HS)-FeIII3 has 216 microstates and HS-FeIII8 ≈ 1.7x106 microstates (S= 5/2). However, complexes with chromium(III) S = 3/2 will have a noticeable reduction of microstates. Mononuclear complexes with formula [mer-CrCl3(pzH*)3] (pz*H = pyrazole, 3-Me-pzH, …
