Abstract: This work describes the synthesis and structural characterization of a novel homo-binuclear coppcr(II) complex [Cu(dinemac)(H2O)2] [Cu(dipic)2].3H2O (1), in which the macrocylic cationic modules are assembled with the anionic components through H bonding. The X-ray siructural analysis indicates that the central atoms Cu(1) and Cu(2) of the two independent cations lic on crystallographic centers of symmetry and that the independent anion with its central atom Cuʹ is sited at a general position. The asymmetric unit of 1 consists of two halves of [Cu(dinemac)(H2O)2]2+ cations, a [Cu(dipic)2]2- anion and three water molecules. The room temperature solid state EPR spectrum of the polycrystalline sample is typical for a non-distorted or exchange averaged mononuclear Cu(II) complex with gav=2.146±0.005 and ΔHpp=9.5 mT.
