Analytische Chemie IV Structure Determination by NMR

Synthesis, Characterization, Luminescent Properties, And Crystal Structure Determination Of a New Platinium (IV) Complexe : trans-[Pt(4-mpy)2Cl4]

The new trans-[Pt(4-mpy)2Cl4] (1) complex (4-mpy is 4-methylpyridine) was prepared from the reaction of H2PtCl6.6H2O with 4-methylpyridine in methanol. Synthesized complex was thoroughly characterized by elemental analysis, IR and 1H-NMR spectroscopy.Elemental analysis data (C, H, N) support the general composition of the title complex and the structure have been established by single-crystal X...

Group (IV) Metallocene Complexes with Bulky ω-aryloxyalkyl-Substituted Indenyl Ligands as Catalyst Precursors for Homogeneous Ethylene Polymerization

 A series of seven new complexes of zirconium and hafnium with bulky ω-aryloxyalkyl substituted indenyl ligands were synthesized and characterized by NMR spectroscopy and elemental analysis. These complexes were activated with methylaluminoxane and tested for homogeneous ethylene polymerization. The zirconium catalysts showed higher activities than their hafnium an...
