Abstract

The octanuclear complex [Eu8L4(1,4-BDC) 2Cl8(MeOH)12] ·4Cl·2MeOH·18H2O (2) was obtained from the reaction of the tetranuclear Eu(III) species [Eu4L2Cl 2(OH)4(H2O)4(MeOH) 2]·2Cl·7MeOH·2H2O (1) and 1,4-H 2BDC (H2L = bis-(5-bromo-3-methoxysalicylidene)ethylene-1, 2-phenylenediamine, 1,4-H2BDC = 1,4-benzenedicarboxylic acid). Both 1 and 2 were structurally characterized by X-ray crystallography, and their luminescence properties were determined. The cagelike structure of 2 encapsulates two chloride anions via MeOH⋯Cl hydrogen bonding. In the solid state, 2 has an open three-dimensional network with extended channels and is capable of reversible MeOH adsorption.
