Popis: | The complex polymer [Cu2(oxap)(fum)]n·5nH2O, where oxap and fum are dianions of N,N′-bis(2-aminopropyl)oxamide and of fumarate, respectively, was prepared and characterized by means of X-ray crystallography, magnetic and spectroscopic measurements. The structure of this compound consists of alternating chains of copper(II) ions bridged by both oxap and fumarate ligands. The central copper atom is located in an approximately square planar environment. The compound exhibits strong anti-ferromagnetic coupling with J = −390 cm−1, due to the efficiency of the oxamidato bridge in propagating antiferromagnetic exchange interaction between copper(II) ions which are separated by more than 5.2 A. |
