Synthesis and X-Ray Structure of (H3O+center-Dot-18-Crown-6)(I-7(-)) - a New Infinite Sawhorse Geometry for I-7(-) Crystallized from a Liquid Clathrate Medium
The synthesis and X-ray crystal structure of [H3O+. 18-crown-6][I-7(-)] isolated from a liquid clathrate medium is reported. The I-7(-) fragment exists in a new infinite sawhorse configuration comprised of I-2 and I- units. The cation exhibits a planar oxonium ion which is symmetrically bound to the crown ether and resides 0.09 Angstrom out of the plane defined by the oxygen atoms of the macrocycle.
