Abstract

Reaction of 1,4-benzenedicarboxylic acid (1,4-H2BDC) with EuCl3·6H2O in MeOH in the presence of Et3N and MeCN gives a mixture of the 3-D metal–organic-framework (MOF) materials [Eu2(1,4-BDC)3(MeOH)4]·8MeOH (1) and 2-D [Eu(1,4-BDC)(MeOH)4]·Cl·MeOH·0.25H2O (2). Similar reactions afforded the isomorphous Gd (3) and Tb (4) analogs of 2. Reaction of 1,4-H2BDC with Ln(NO3)3·6H2O under similar conditions gave [Ln(BDC)NO3(MeOH)2]·MeCN·H2O (Ln = Eu (5) and Gd (6)), which have 2-D framework structures. The structures of 1–6 were determined by single crystal X-ray crystallographic studies and the luminescence properties of 1 and 4 in DMF solution were determined.
