Abstract Three new lanthanide-organic compounds, namely, [Ln2(OH)2(oba)(2-pc)2]n (Ln = Er (1), Ho (2), and Dy (3)) (oba = 4,4΄-oxybis(benzoate), 2-pc = 2-pyrazinecarboxylic acid) have been obtained under hydrothermal conditions. These compounds are isostructural and exhibit 2D layered structures by incorporating [Ln4(μ3-OH)4]8+ clusters and the mixed linkers of oba and 2-pc. It is interesting that decarboxylation occurred in the ortho position and 2,3-pyrazinedicarboxylic acid was partially transformed into 2-pc under hydrothermal conditions. Compound 3 emits a typical Dy3+ emission spectrum. Furthermore, the PXRD, TGA and IR spectra were also studied.
