Cu²⁺‐Mediated Dehydrogenative Coupling and Hydroxylation of an N‐Heterocyclic Ligand: From Generation of a New Tetratopic Ligand to the Designed Assembly of Three‐Dimensional Copper(<scp>I</scp>) Coordination Polymers

Abstract

The hydrothermal reaction of 1,3-di(4-pyridyl)propane with Cu(OH)2 in the presence of 1,4-cyclohexanedicarboxylic acid and dilute HCl generates an unprecedented tetratopic ligand (chtpy) and a family of interesting coordination networks in situ (see scheme). The topological diversification of the CuI–chtpy nets can be controlled simply by changing the molar ratio of the starting materials.
