Synthesis, Structure, and Magnetism of a Novel Alkoxide Bridged Nonacopper(II) (Cu9O12) [3×3] Square Grid Generated by a Strict Self-Assembly Process

Abstract

A ligand with a linear arrangement of three coordination pockets produces a Cu9O12, alkoxide-bridged, square grid of closely spaced copper centers (see picture) in high yield by a strict self-assembly process. Orthogonal bridging connections within the grid lead to dominant intramolecular ferromagnetic coupling with a high-spin ground state.
