Synthesis, structures, catalytic, and anticancer activities of some coordination compounds involving two new triazole derivatives
摘要:
Five N-heterocyclic carboxylate based coordination complexes are synthesized which all show hydrogen bonding supramolecular structures, and the photocatalytic and anticancer activities of them are investigated.Five N-heterocyclic carboxylate-based coordination complexes, [Co(L-1)(2)(H2O)(2)]2H(2)O (1), [Cd(L-1)(2)(H2O)(2)]2H(2)O (2), [Co(L-2)(H2O)(3)] (3), [Ni(L-2)(H2O)(3)] (4), and [Cu-2(L-2)(2)(H2O)(2)] (5), have been synthesized and characterized by elemental analysis, IR spectroscopy, Powder X-ray diffraction, thermogravimetric analyses, and single-crystal X-ray crystallography, where HL1 is 2-((5-amino-1H-1,2,4-triazol-3-yl)thio)acetic acid and H2L2 is 2-((5-amino-1-(carboxymethyl)-1H-1,2,4-triazol-3-yl)thio)acetic acid. In these complexes, the hydrogen bonds (H-bonds) play an important role in their packing structures. Complex 1 has nine H-bonds showing a 3-D sqc38 topology. Complex 2 has 17 H-bonds exhibiting a 3-D hxl network. Complexes 3 and 4 are isomorphic, both of which possess ten H-bonds to present a 3-D btc topology. Complex 5 with eight H-bonds forms a 2-D sq1 structure. In addition, complex 3 catalyzes the decolorization of methyl orange. Meanwhile, 1, 3, and 5 show certain anticancer activities to inhibit the growth of HepG2 cells.
