摘要
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.

The complex is composed of copper cations, sulfate anions, 1, 10-phenanthroline, protocatechuic acid and lattice water molecules. The structure of H(3)PCA, SO42- and waters comprises packing of anionic three-dimensional network by hydrogen bonds with cavities. The complex can be considered as a model of host/guest supramolecule. The three-dimensional hydrogen-bonding network is the host species. The Cu(phen)3(2+), cations, guest species, occupied the cavities of the host. And the results demonstrate that the form of protocatechuic acid at pH < 1 should be free ligand. CCDC: 191733.
