Structural Insights into New Bi(III) Coordination Polymers with Pyridine-2,3-Dicarboxylic Acid: Photoluminescence Properties and Anti-Helicobacter pylori Activity

Abstrakt

Two novel coordination polymers, [Bi2(2,3pydc)2(2,3pydcH)2(H2O)]n(1) and {(Et3NH)2[Bi(2,3pydc)(2,3pydcH)Cl2]}n(2) were prepared using as a prolinker pyridine-2,3-dicarboxylic acid(2,3pydcH2). The obtained complexes were fully characterized by elemental analysis, TG/DTG, FT-IR,solid-state photoluminescence, DFT calculations and single-crystal X-ray diffraction. The obtainedcomplexes crystallized in the triclinicP-1 space group (1) and comprise dimeric units with twocrystallographically different Bi(III) centers (polyhedra: distorted pentagonal bipyramid andbicapped trigonal prism) and monoclinicP21/cspace group (2) with a distorted monocappedpentagonal bipyramid of Bi(III) center. The various coordination modes of bridging carboxylateligands are responsible for the formation of 1D chains with4,5C10(1) and2C1(2) topology.The photoluminescence quantum yield for polymer2is 8.36%, which makes it a good candidate formore specific studies towards Bi-based fluorescent materials. Moreover, it was detected that polymer1is more than twice as active againstH. pylorias polymer2. It can be concluded that there is anexisting relationship between the structure and the antibacterial activity because the presence ofchloride and triethylammonium ions in the structure of complex2reduces the antibacterial activity.
