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

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 (1). Single-crystal X-ray diffraction revealed that 1 has anionic [(1,3-Hbdc)4(H2O)9.5]n4n− water cluster chains that are encapsulated into the 1D channels of a 3-D [Cu8Cl4(bpp)8]n4n+ cationic framework. The thermal and luminescent properties of 1 in the solid state were also investigated.

Reactions of CuCl with 1,3-bis(4-pyridyl)propane (bpp), 1,3-benzenedicarboxylic acid (1,3-H2bdc), KOH under hydrothermal conditions produced {[Cu8Cl4(bpp)8][(1,3-Hbdc)4(H2O)9.5]}n, in which anionic [(1,3-Hbdc)4(H2O)9.5]n4n− water cluster chains are enclosed into the 1D channels of a 3D [Cu8Cl4(bpp)8]n4n+ cationic framework.Figure optionsDownload as PowerPoint slide
