Self‐Assembly of Polyanions at a Metal Cation Template: Syntheses and Structures of Ag ([18aneS6) I7]n and Ag ([18aneS6) ]I3

A distorted cubic lattice of I ions, in whose cavities the complex cations Ag([18aneS6)]+ (18aneS6 = 1,4,7,10,13,16-hexathiacyclooctadecane) are encapsulated, is formed in the synthesis of 1 (section of structure shown on the right). I− ions are positioned at the lattice points; one I2 molecule is located along each edge. The Ag+ ions function as a secondsphere template in the synthesis of the I polyanion.
