Synthesis, structures and antibacterial activities of two complexes of yttrium (III) with 2,6-pyridinedicarboxylate

Two novel complexes, Na3Y(pydc)3·12H2O (1) and Y2(pydc)(OH)4·3H2O (2) (pydc = 2,6-pyridinedicarboxylate), were synthesized by yttrium (III) nitrate and pydcH2 with different molar ratios. The elemental analysis, IR spectra and single crystal X-ray diffraction were used to determine the structure of complexes. The thermal decompositions and antimicrobial activities against Bacillus coli and Staphylococcus aureus were recorded and interpreted for both.

Graphical abstractTwo novel complexes, Na3Y(pydc)3·12H2O (1) and Y2(pydc)(OH)4·3H2O (2) (pydc = 2,6-pyridinedicarboxylate), have been synthesized by the reaction of yttrium (III) nitrate with pydcH2 in different molar ratios, and characterized by elemental analysis and IR. Thermal decompositions and antimicrobial activities against Bacillus coli and Staphylococcus aureus have been recorded and interpreted for both. The crystal structure of complex 1 is determined by single crystal X-ray diffraction and the possible structure of complex 2 is also described.Figure optionsDownload full-size imageDownload as PowerPoint slide
