Iodophosphane Selenides: Building Blocks for Supramolecular Soft-Soft Chain, Helix, and Base-Pair Arrays

Abstract

A novel type of P=Se⋅⋅⋅I−P bridging is found in the solid-state structures of iodophosphane selenides. These molecules can be viewed as new building blocks for the design of directed donor–acceptor interactions (see diagram) within chains, helices and “soft–soft” base pairs.
