A novel supramolecular compound [CuCl(4,4ˊ-bipy)]n has been rationally designed and synthesized by hydrothermal method and the structure was characterized with elemental analysis,FT-IR spectrum and X-ray diffractometer.It crystallizes in the monoclinic,space group P2(1)/c,with a=0.37733(8) nm,b=1.2711(3) nm,c=1.1403(2) nm,β=94.15(3) °,V=0.54547(19) nm3 and Z = 4.The title compound contains the extended one-dimensional staircase chain n.In the packing structure,weaker intermolecular C-H…Cl hydrogen-bonded and π-π interactions are the most significant factors of controlling the novel supramolecular sheet fashion.
