| 摘 要： | Under hydrothermal conditions,a new lanthanide coordination polymer,Er3(oba)4(na)]n(1,oba=4,4?-oxybis(benzoate),na=nicotinic acid)has been synthesized.Compound 1 shows a 3D framework by incorporating tri-nuclearEr3(COO)6]unit and the mixed ligands of oba2-and na-.It is interesting that decarboxylation occurred in the ortho position and 2,3-pyridinedicarboxylic acid was partially transformed into na under hydrothermal conditions.Compound 1 can be reduced into a(3,11)-connected net and displays weak second-harmonic generation response.Furthermore,the PXRD,TGA and IR spectra were also studied.

| Abstract: | Under hydrothermal conditions, a new lanthanide coordination polymer, Er_3(oba)_4(na)]n(1, oba = 4,4'-oxybis(benzoate), na = nicotinic acid) has been synthesized. Compound 1 shows a 3D framework by incorporating tri-nuclear Er_3(COO)_6] unit and the mixed ligands of oba~(2-)and na~-. It is interesting that decarboxylation occurred in the ortho position and 2,3-pyridinedicarboxylic acid was partially transformed into na under hydrothermal conditions. Compound 1 can be reduced into a(3,11)-connected net and displays weak second-harmonic generation response. Furthermore, the PXRD, TGA and IR spectra were also studied. |
