摘要

Two 2D zinc(II) layered coordination polymer compounds [Zn_ 2(atz)_2(na)_2]_n (1), and [Zn(atz)(ina)]_n (2) (Hatz = 3-amino-1H-1, 2, 4-triazole, na = nicotinic acid, ina = isonicotinic acid) were synthesized and structurally characterized by elemental analysis, FT-IR, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), and single-crystal X-ray diffraction. The interconnection of a coplanar six-membered hexagonal ring and a 16-membered non-planar chair-like ring results in a 2D sheet with (4, 8~2) topological network. Hydrogen bonds connect the neighboring planes into 3D supramolecular architectures. Furthermore, both complexes exhibit strong luminescent properties in the solid state at room temperature.
