Abstract
By reaction of N-benzoylthiocarbamic-O,S-diethyl-ester with primary diamines (oxa)alkylene bridged isoureas 1 have been prepared. They yield with CuII neutral chelates 2 with tetradentate ligand coordination. The structures of the ligand la and of the related CuII complex 2a 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.
