A novel independent one-dimensional (1D) coordination polymer nanotube [Cd3(BPT)2(phen)3(H2O)]·4.5H2O (CPNT-1, H3BPT = biphenyl-3,4′,5-tricarboxylic acid; phen = 1,10-phenanthroline) has been synthesized and structurally characterized. CPNT-1 shows a fascinating 1D → 2D interdigitated architecture, and the final three-dimensional supramolecular columnar network was formed via π–π stack interactions between the terminal phen ligands of the coordination polymer nanotubes. Luminescent studies show that CPNT-1 displays strong green emission at room temperature, and the guest water molecules affect its luminescent properties.
