Cu(I) and Cu(II) coordination polymers of 1,10-dithia-18-crown-6 (L) with unusual networking modes involving an exocyclic coordination are presented. The reaction of L with copper(II) nitrate gave a unprecedented ladder-type 1D coordination polymer {[(L(OX)) Cu(2)(NO(3))(2)(H(2)O)(4)](L(OX)) (NO(3))(2)center dot(2)H(2)O}(n) (1) via strong Cu(II)-O(sulfoxide) bonds because L was oxidized to the disulfoxide macrocycle (L(OX)) under the present conditions. Meanwhile the parallel reaction of copper(I) iodide with L in the presence of cobalt(II) perchlorate yielded a mixture of an emissive 2D network product [(Cu(4)I(4))(L)(2)](n) (2) linked with cubane- type C u(4)I(4) clusters and a non-emissive 1D coordination polymer {[(Cu(2)I(2))(L)(2)][Co(H(2)O)(6)](ClO(4))(2) center dot 0.5H(2)O}(n) (3) linked with rhomboidal Cu(2)I(2) cores. In 3, hexaaquacobalt(II) complexes, anions and water molecules also exist and stabilize the 1D macrocyclic network through H-bonds.
