超分子三维氢键网络:{[Cu（phen）3]（SO4）(H3PCA)2（8H2O）}的晶体结构

A new complex,｛[Cu(phen) 3 ](SO 4 )(H 3 PCA) 2 (8H 2 O)｝,was synthesized and structurally c haracterized by single-crystal X-ray analysis.The complex is composed of copper cation s,sulfate anions,1,10-phenanthro line,protocatechuic acid and lattice water molecules.The structure of H 3 PCA,SO 42- and waters comprises packing of anionic three-dimensional network by hydrogen bonds with cavities.The complex can be considered as a model o f host /guest supramolecule.The thre e-dimensional hydrogen-bonding network is the host species.The Cu(phen) 32+ cations,guest species,occupied th e cavities of the host.And the results demonstrate that the form of protocatechuic acid at pH <1should be free ligand.CC DC:191733.
