Cage^-···Cage^- Interaction: Boron Cluster-Based Noncovalent Bond and Its Applications in Solid-State Materials.

ABSTRACT: Carboranes are boron-carbon clusters with important applications in the fields of materials, catalysis, pharmaceuticals, etc. However, the noncovalent interactions that could determine the solid-state structures and properties of such boron clusters have rarely been investigated. Herein, inspired by the coordinate bond in metallacarborane or ferrocene, the boron cluster-based noncovalent interaction (denoted as cage^-···cage^- interaction) between two nido-carborane clusters was successfully realized by using a pyridinium-based molecular barrier. The X-ray diffraction studies uncover that the cage^-···cage^- interaction has a contacting distance of 5.4-7.0 Å from centroid to centroid in the systems reported here.
