All the obtained compounds were characterized by single-crystal X-ray diffraction analysis. In the complexes, 2,6-bis(5-trifluoromethylpyrazol-3-yl) pyridine exists in the neutral and dianionic forms and exhibits different coordination modes (κ3-, μ2-κ3: κ1-, and μ3-κ3: κ1:κ1). The electrochemical and magnetic properties of all compounds were studied. The tetranuclear NiII complex with the L2- dianion is reduced in two sequential reversible one-electron steps \\\\Expert2\\NBO\\Russian Chemical Bulletin\\2012, 61 (2), 313-325.pdf |
