Kurzfassung englisch:
The flexible ditopic ligand 1,3-bis[5-(2-pyrimidinyl)-1,2,4-triazol-3-yl]propane H2L displays remarka-ble versatility in the coordination mode depending on the counter anion. With copper(II) nitrate H2L acts as a tetradentate chelate forming a mononuclear complex. The reaction with copper(II) perchlorate gives a centrosymmetric dinuclear complex coordinating the deprotonated form of the ligand. Reaction with copper(II) chloride leads to a pentanuclear complex in which binuclear species are bridged by a CuCl2 fragment. All complexes were crystallographically characterized. Additionally, magnetic prop-erties of bi- and pentanuclear complexes were studied.
