  • Original language description

    A series of tetramethyl-(Cp') and pentamethylcyclopentadienyl (Cp*) metal complexes (eta(5)-C5Me4R) ZrCl2LCO (R = H(1), Me(2)) and (eta(5)-C5Me4R)HfCl2LCO (R = H(3), Me(4)) where L-CO is a bifunctional beta-diketiminate ligand [2-(MeO)-C6H4)]NC(Me)CHC(Me)N[2-(MeO)-C6H4)] (L-CO) were prepared from corresponding tetramethyl-and (pentamethylcyclopentadienyl) metal trichlorides and the lithium precursor LiLCO. All complexes were characterized by their melting point, elemental analysis, H-1 and C-13 NMR spectroscopy, IR spectroscopy. In addition their solid-state structures were determined by X-ray diffraction techniques. In all cases, a pseudo-tetragonal pyramidal coordination environment of the metal centre with cyclopentadienyl ligand on the top and nearly isobidentately bonded nitrogen atoms of the chelating L-CO ligand in an open eta(5)-fashion was observed. The oxygen atoms positioned at the diketiminate periphery remained uncoordinated to transition metal in the solid phase as well a
