Two kinds of single crystal complexes [Zn (IHQS) (H 2 O) 3] 2 · 4H 2 O (1) and ZnCl 2 were synthesized for zinc (II), cadmium (II) and 7 iodine 8 hydroxyquinoline 5 sulfonate (IHQS) The structure was confirmed by X-ray diffraction (XRD). The results showed that both 1 and 2 were composed of a pair of enantiomeric complexes: 1 [2 (OHQS) The enantiomer of Zn (IHQS) (H2O) 3] forms a central symmetrical bimodal polymer through the axial complementary coordination of the sulfonate-zinc (II) octahedron. The polymer is coordinated by the intermolecular sulfonate oxygen- The two hydrogen bonds of [Cd (IHQS) (H 2 O) 2] 2 form a one-dimensional two-way complementary coordination through Cd (II) sulfonate- A linear iodine group exhibits a novel mode of weak interaction such as iodine-aromatic ring hydrogen and iodine-sulfonic acid oxygen, and plays an important structural aiding role in the stabilization of the above structure.In this paper, aromatic iodine Structure, Space Matching and Synergistic Promoting Mechanism of Three Weakly Interacting Groups of Sulfonates and Quinoline Rings in Coordination Supramolecular Self-assembly Crystallography Parameters Complex 1: monoclinic, C2 / c space Group, a = 2 2 2 (4) nm, β = 102267 (5) °, V = 2942 8 (16) nm3 and Z = 4342 nm, b = 1 0 0 3 3 nm, c = 1 3 468 nm, = 4.
