Abstract
Abstract Two nickel(II) complexes, [Ni(acac) 2 (dmpeO 2 )] n ·2CHCl 3 ( 1 ) and [(Ni(acac)(MeO)(MeOH)] 4 ( 2 ) (acac − = pentane-2,4-dionato) have been synthesized and characterized by elemental analysis, FT-IR spectroscopy, and single crystal X-ray diffraction. The geometries around the central nickel(II) ion are distorted octahedral in both complexes. The equatorial plane includes four oxygen donor atoms of two acetylacetonato ligands and the axial positions are occupied by two oxygen atoms of two dmpeO 2 ligands. Complex 1 has a polymeric chain structure in the solid state, while complex 2 has a tetranuclear cubane structure. These complexes are the first reported examples of polymeric and tetranuclear structures of Ni((II) containing acac - ligand. Neither complex is catalytically active for the hydrogenation of CO 2 to formamide, even though a mixture of Ni(acac) 2 and dmpe form a very active in situ catalyst together.
