Synthesis, X-ray crystal structures, and luminescent properties of two coordination polymers constructed from transition metal complexes of mixed flexible–rigid ligands

Two new coordination polymers [Ni(C6H10O4)(C10H8N2)] n (1) and [Zn3(C6H10O4)3(C12N2H8)2] n (2) have been synthesized under hydrothermal conditions. Complex (1) exhibits an interesting three-dimensional interpenetrating network, whereas complex (2) has a two-dimensional network. The IR and TG properties of these two complexes are studied. Furthermore, complex (2) exhibits photoluminescence.
