Encapsulation of unique anionic carboxylic acid/water cluster chains into channels of a three-dimensional cationic framework

摘要

The hydrothermal reactions of CuCl with 1,3-bis(4-pyridyl)propane (bpp), 1,3-benzenedicarboxylic acid (1,3-H2bdc), and KOH in water afforded {[Cu8Cl4(bpp)8][(1,3-Hbdc)4(H2O)_(9.5)]}_n. Single-crystal X-ray diffraction revealed that 1 has anionic [(1,3-Hbdc)4(H2O)_(9.5)]_n~(4n-) water cluster chains that are encapsulated into the 1D channels of a 3-D [Cu8Cl4(bpp)8]_n~(4n+) cationic framework. The thermal and luminescent properties of 1 in the solid state were also investigated,
