Two novel tetranuclear zinc(II) clusters with different topological structures: Crystal structures and luminescence properties

Two new Zn(II) complexes have been successfully synthesized under the identical experimental conditions. Due to the different types of R substituents in Schiff base ligands, complexes 1 and 2 exhibit linear and square-planar tetranuclear structures respectively. The fluorescence properties of these two complexes have also been investigated.
