Complex 1 presents a 2 D layer structure, which is finally packed into a 3 D supramolecular structure by means of hydrogen bonds;complexes 2 and 3 exhibit 1 D chains and 2 D wavy-type structures, respectively, which are expanded into 3 D supramolecular structures through hydrogen bonds and π-π interactions. Furthermore, the luminescence properties of complex 1 and the variable-temperature magnetic susceptibilities of 3 were investigated. Complex 1 has highly selective sensing for Fe^3+ and Cr2O7^2- ions.展开更多
