主 题:zigzag chain heterobimetallic metalloligand crystal structure fluorescence
摘 要:Two new heterobimetallic coordination polymers{[Co(NiL)(H2O)3]·4H2O}n(1)and{[Cu(NiL)(H2O)3]·4H2O}n(2)were synthesized based on metalloligand under the same self-assembly conditions.X-ray diffraction analyses reveal that the two compounds involve close-packed zigzag chains,which expand into various three-dimensional supramolecular frameworks through the second interactions such as hydrogen bonds andπ···πstacking *** these two compounds,NiL as a bridging ligand chelates the metal ion nodes via two oxamido carbonyls and carboxylate oxygen *** central Co(Ⅱ)and Cu(Ⅱ)ions in 1 and 2 both exhibit distorted octahedral coordination *** are bridged by macrocyclic oxamido metalloligands fusing the zigzag chains with a‘‘head-to-tail’’*** Ni(Ⅱ)ion in metalloligand is coordinated by four nitrogen atoms with the[NiN4]chromophore exhibiting distorted *** two investigated compounds were further characterized by thermogravimetric analysis and FT-IR *** fluorescent properties of 1 and 2 in the solid state were also investigated.
