Two novel luminescent zinc supramolecular networks with nicotinate derivatives by hydrothermal process

Two novel zinc compounds with nicotinate derivatives, [Zn(Enic)2]n and [Zn(H2O)6][6-OHnic]2, have been synthesized under hydrothermal reaction conditions. The X-ray single-crystal analysis reveals that the structure of the compound 1 is self-assembled from square-grid nets stacked via interdigitation while compound 2 forms a 3D supermolecular network structure via strong O-H⋯O hydrogen bond.
