Abstract

Abstract : Graphical abstract: The flexible ditopic ligand 1, 3-bis[5-(2-pyrimidinyl)-1, 2, 4-triazol-3-yl]propane H2 L displays remarkable versatility in the coordination mode depending on the counter anion. Abstract: The flexible ditopic ligand 1, 3-bis[5-(2-pyrimidinyl)-1, 2, 4-triazol-3-yl]propane H2 L displays remarkable versatility in the coordination mode depending on the counter anion. With copper(II) nitrate H2 L 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 properties of bi- and pentanuclear complexes were studied.
