Mononukleare Kupfer(II)-Komplexe von dioxaalkylenund alkylenverbrückten Bis-isoharnstoffen
摘要:
By reaction of N-benzoylthiocarbamic-O,S-diethyl-ester with primary diamines (oxa)alkylene bridged isoureas I have been prepared. They yield with Cu-II neutral chelates 2 with tetradentate ligand coordination. The structures of the ligand 1a and of the related Cu-II complex 2 a have been determined by X-ray crystal structure analysis. They show an enamine tautomer in the ligand and a slightly tetrahedrally distorted coordination with an (oxa)alkylene bridge between the trans arranged N ligator atoms in the complex.
