合成了一种新的四核配合物{[Cu（phen）（OH）]4（H2O）2} ·（SO 4）2 ·8H 2 O（1）（phen = 1，10-菲咯啉），并通过元素分析、紫外-可见光谱、红外光谱、热重分析和单晶X-射线衍射对其进行了表征。配合物1为三维超分子网络结构，一维金属-水链由四核羟基桥联的铜（II）簇和水八聚体组成，二维水-硫酸盐层由五种O-H ··· O氢键模式的环状水八聚体组成.筛选了游离配体及其配合物对革兰氏阳性菌和革兰氏阴性菌的抗菌活性。
A new tetranuclear complex, {[Cu(phen)(OH)]4(H2O)2} · (SO4)2 · 8H2O (1) (phen = 1,10-phenanthroline), has been synthesized and characterized by elemental analysis, UV-Vis, IR, TG, and single-crystal X-ray diffraction. Complex 1 exhibits a 3-D supramolecular network with a 1-D metal–water chain consisting of tetranuclear hydroxo-bridged copper(II) clusters and water octamers and a 2-D water–sulfate layer containing cyclic water octamers with five types of O–H ··· O hydrogen-bonding motifs. The free ligand and its complex were screened for antibacterial activity against Gram-positive and Gram-negative bacteria.
