摘  要:Molecular structure of a naphthyridine and pyrazine amine ligand, N2,N7-di(pyrazin-2-yl)-1,8-naphthyri-dine-2,7-diamine(H2dpznda 1) was studied, and a three-dimensional supramolecular network with a double helix chain structure through intermolecular hydrogen bonds and π-π interactions between the naphthyridine and pyrazine rings was depicted. Through ligand 1, [Co2(μ2-dpznda)2(μ2-CH3OH)2](2) was obtained and two ligands coordinate to two Co2+)as tetradentate bridging ligands. Single crystal and magnetism study on 2 revealed that the complex exhibited weak yet significant metal-metal interaction.Molecular structure of a naphthyridine and pyrazine amine ligand, N2,N7-di(pyrazin-2-yl)-1,8-naphthyri-dine-2,7-diamine(H2dpznda 1) was studied, and a three-dimensional supramolecular network with a double helix chain structure through intermolecular hydrogen bonds and π-π interactions between the naphthyridine and pyrazine rings was depicted.
