Abstract

Two kinds of iodine-iodine halogen bonds are the focus of our attention in the crystal structure of the title salt, C<subscript>12</subscript>H<subscript>8</subscript>ClINO<superscript>+</superscript>·I<subscript>3</subscript><superscript>−</superscript>, described by X-ray diffraction. The first kind is a halogen bond, reinforced by charges, between the I atom of the heterocyclic cation and the triiodide anion. The second kind is the rare case of a halogen bond between the terminal atoms of neighbouring triiodide anions. The influence of relatively weakly bound iodine inside an asymmetric triiodide anion on the thermal and Raman spectroscopic properties has been demonstrated. [ABSTRACT FROM AUTHOR]
