Abstract
[Yb2(SBTC)(ox)(H2O)5]n (1) (H4-SBTC = 5-sulfonyl-1,2,4-benzenetricarboxylic acid and ox = oxalate) has been hydrothermally synthesized by reaction of 5-sulfonyl-1,2,4-benzenetricarboxylic acid with Yb(NO3)3∙5H2O. In situ formation of oxalate derived from H4-SBTC is unprecedented and adds a new oxalate formation reaction to in situ ligand syntheses. Compound 1 features a 2-D bilayered coordination network, which is further extended into a 3-D supramolecular framework through interlayered hydrogen bonds. Magnetic measurements on 1 indicate that there is an antiferromagnetic interaction between Yb(III) ions.
