A novel lanthanide coordination polymer formulated as [Nd(dpdo)4(H2O)3][ClO4]4·4.5H2O·dpdo1(dpdo=4,4′-dipyrazine-dioxide)was synthesized and structurally characterized.The Nd3+ions are bridged by dpdo ligands in a cis-mode to form a zigzag chain along[001]direction.Meanwhile,each Nd3+ion is coordinated with three terminal dpdo molecules.One of them is overlapped with the bridging one throughπ－πstackings,and the orher wto are bound to the opposite directions of the bridging ones,producing a ribbon-like motif with rectangular cavity,These adjacent ribbons are connected thorough inter-molecularπ－πstackings to give parquet-like architecture with a large rectangular channel(1.108nm×1.660nm)in which the crystal lattice water molecules and ClO-4anions are included.Thermalanalysis shows that the solvate dpdo and water molecules can be removed at lower temperature,while coordinated dpdo molecules are lost simultaneously at higher temperature.
