Flexiblemeso-Bis(sulfinyl) Ligands as Building Blocks for Copper(II) Coordination Polymers: Cavity Control by Varying the Chain Length of Ligands

Abstract
Fillings and cavities: Three novel pseudo‐octahedral metal–organic frameworks, 1–3, consisting of macrometallacyclic noninterpenetrating meso networks and exhibiting weak antiferromagnetic interactions, have been constructed from CuII centers and structurally flexible R,S‐bis(sulfinyl) ligands. Varying the chain length of ligands is found to control the cavity sizes of the networks.
