Abstract
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 (μ 2-dpznda) 2 (μ 2-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.
