Self-organizing super-structures formed from hydrogen-bonded biimidazolate metal complexes

Abstract

Manipulation of molecular crystals formed from self-organization is one of the important methods to develop the new molecular functional materials. In particular, we look upon mutual cohesive interactions of hydrogen bonding and metal coordination as one useful tool to construct the preprogramming superstructures. In this study, five controlled superstructures of a one-dimensional linear chain--a zigzag ribbon, right-handed and left-handed helices, and a two-dimensional honeycomb sheet--are newly created by using the neutral metal complexes with some 2,2'-biimidazolate mono-anions.
