Abstract: Two new zinc coordination polymers based on N-[(3-Pyridine)-sulfonyl]amino acid ligand have been synthesized and characterized by single-crystal X-ray diffraction and elemental analysis. The results show that the 1 is a two-dimensional structure coordination polymer and synthesized under room temperature condition; the 2 is a three-dimensional structure coordination polymer and synthesized under hydrothermal synthesis condition. These two structures are formed by 4,4′-dipyridy and 4,4′-azpy for 1 and 2, respectively. A structural comparison of these two coordination polymers suggests that different reaction temperatures play important role in the construction of resulting architectures of 1 and 2. Fluorescence measurements show that 1 has medium fluorescent emission at 374 nm and 2 has medium fluorescent emission at 438 nm.
