The protonation and metal complex formation of the branched pentaamine ligand 2,2,6,6-tetrakis(aminomethyl)-4-azaheptane (ditame, L) with CoII, CoIII, NII, CuII, ZnII, and CDII have been studied. The crystal structures of [Ni(ditame)(EtOH)] Br2, [CO2(ditame)2(O2)Cl4 ·4H2O, and [Co2-(ditame)2(O2)]Cl2 [ZnCl4][ZnCl3(H2O)]·H2O were determined by X-ray diffraction analyses. The metal complexes showed octahedral coordination geometries with exclusive formation of six-membered chelate rings, the four...[Show more]
