A novel lanthanide coordination polymer formulated as [Nd(dpdo)4(H2O)3] [ClO4]3*4.5H2O*dpdo 1(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 N d3+ ion is coordinated with three terminal dpdo molecules. One of them is overlapped with the bridging one through π-π stackings, and the other two are bound to the opposite directions of the bridging ones, producing a ribbon-like motif with rectangular cavity. These adjacent ribbons are connected through int er-molecular π-π stackings to give parquet-like architecture with a large re ctangular channel (1.108 nm×1.660 nm) in which the crystal lattice water molecu les and ClO4- anions are included. Thermal analysis shows that the solvate d pdo and water molecules can be removed at lower temperature, while coordinated d pdo molecules are lost simultaneously at higher temperature.
