In the title compound, {[Cu(CHO)(CHNO)]·5HO}, the Cu cations are coordinated in a square-pyramidal fashion, with four 3-(2-carb-oxy-phen-yl)propionate (cpp) carboxyl-ate O-atom donors in the basal plane, along with an N-atom donor from a -[2-(pyridin-3-yl-amino)-eth-yl]nicotinamide (pen) ligand in the apical position. [Cu(cpp)] coordination polymer layer motifs with embedded {Cu(OCO)} paddlewheel clusters are thereby constructed. These layer motifs are connected into a three-dimensional [Cu(cpp)(pen)] coordination polymer network by tethering pen ligands. Treating the {Cu(OCO) paddelwheel clusters as 6-connected nodes reveals an underlying cross-pillared self-penetrated network with 468 topology. The water mol-ecules of crystallization are held to the coordination polymer network by N-H⋯O and O-H⋯O hydrogen-bonding patterns.
在标题化合物{[Cu(CHO)(CHNO)]·5HO}中，铜阳离子以四方锥构型配位，四个3-(2-羧基苯基)丙酸酯（cpp）羧酸根O原子供体位于基面，一个来自-[2-(吡啶-3-基氨基)乙基]烟酰胺（pen）配体的N原子供体位于顶端位置。由此构建了具有嵌入{Cu(OCO)}桨轮簇的[Cu(cpp)]配位聚合物层结构单元。这些层结构单元通过连接pen配体连接成三维[Cu(cpp)(pen)]配位聚合物网络。将{Cu(OCO)桨轮簇视为6连接节点，揭示了一个具有468拓扑结构的潜在交叉柱撑自穿透网络。结晶水分子通过N-H⋯O和O-H⋯O氢键模式与配位聚合物网络相连。
