Abstract
The 2,11-dithia[3.3](3,5)pyrdinophane (L1) has been synthesized by a new method and characterized by 1H NMR, which is used to form coordination complexes C14H14N4O6S2Ni (I) by addition of Ni2+ cation and C14H14N3O3S2Ag (II) by addition of Ag+ cation. 2,11,20-Trithia[3.3.3](3,5)pyridinophane (L2) and 2,11,20,29-tetrathia[3.3.3.3](3,5)pyridinophane (L3) have also been synthesized as by-products. Single-crystal X-ray analysis reveals that the conformation of the L1 is syn(boat-chair), complexes I and II also adopt syn(boat-chair) (CIF files CCDC nos. 1400332 (I) and 700724 (II)). While in I, Ni(II) is coordinated with L1 with two nitrogen and four oxygen atoms, in II, Ag(I) is coordinated with L1 by two nitrogen and two sulfur atoms came from four ligands. In complexes I and II, the formation of three-dimensional structure depends on π⋅⋅⋅π stacking and hydrogen bonds.
