Solvothermal syntheses and crystal structures of new Cu(II) complexes with phenylsuccinic acid

Five Cu(II) complexes with phenylsuccinic acid and diamine-like ligands were obtained under solvothermal conditions, and complexes 2 and 3 were obtained in one-pot reaction. Complexes 1-3 and 5 are composed of [psa]2− and terminal ligands phen, 2bpy, and N3- resulting in 2D and 3D supramolecular networks, and complex 4 forms a 3D metal-organic framework by bridging ligands [psa]2− and 4bpy.
