Synthesis and Structures of Bidentate Lewis Acid Complexes R[OB(C6F5)2]2 (R = C2H4, p-C6H4) with Pyrazine

Abstract

Single crystals of complexes between bidentate Lewis acids R[OB(C₆F₅)₂]₂ (R = C₂H₄, p-C₆H₄) and pyrazine (pyz) are obtained for the first time and characterized by the single crystal X-ray diffraction analysis. Despite the possible formation of polymeric compounds, there is the monodentate coordination of pyrazine molecules to each of boron atoms of bidentate acid.
