Solution assembly of heterocyclic disulfide ligand, 4‐ppds {4‐ppds = bis[4‐(pyridin‐4‐yl)pyrimidinyl]disulfide}, with Cu(OAc) 2 and ZnI 2 resulted in two 1D (one‐dimensional) coordination polymers 1 and 2 , which were well characterized by infrared spectroscopy, elemental analysis, powder X‐ray diffraction, single‐crystal X‐ray diffraction, diffuse‐reflectance UV/Vis as well as photoluminescence spectroscopy. Single crystal X‐ray crystallography discloses that 1 shows an achiral zigzag chain structure built up by alternate linking of paddlewheel Cu 2 (OAc) 4 dicopper unit and 4‐ppds ligand with opposite configurations, whereas 2 exhibits a helical chain structure constructed by alternate linkage of tetrahedral zinc atom and 4‐ppds ligand with the same chirality ( P ‐ or M ‐configuration). It is supposed that the flexible coordination environment around the tetrahedral Zn II ion might be beneficial to homochiral arrangement of 4‐ppds ligand.
