A new 2D Cd(II) coordination polymer, [Cd(BBI) 4 Cl 2 ] n (BBI = 1,1′-(1,4-butanediyl)bis (imidazole)) ( 1 ), was synthesized under hydrothermal conditions, and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction crystallography. For complex 1 , each Cd(II) ion crystallizes in a [CdN 4 Cl 2 ] six-coordinated slightly distorted octahedral geometry, coordinating to four BBI ligands by Cd–N bonds, completed by two terminal Cl − anions. The characteristic of 2D grid-like layers, from the central Cd(II) ions as knots and BBI ligands as spacers, is the hetero-chiral helical chains of left- and right-hand helixes. Two kinds of π interactions assemble 2D layers into 3D supramolecular architecture in an ···ABC··· packing arrangement. The fluorescent properties were studied in the solid state for its luminescent applications.
