Constructing an 8-Connected Hydrogen-Bonded Organic Framework with Hafnium-Oxo Clusters.

ABSTRACT: Hydrogen-bonded organic frameworks (HOFs) exhibit intriguing structural features with potential applications in various fields. However, constructing HOFs based on high-connectivity nodes is a challenging task. In this study, we report the synthesis of three new metal-hydrogen-bonded organic frameworks (M-HOFs), Hf₄-P4/n, Hf₄-Fddd-1, and Hf₄-Fddd-2, based on a charge-neutral tetranuclear hafnium-oxo cluster [Hf₄(μ₂-OH)₈L₈] (L = 1H-benzimidazole-2-carboxylate) as the building unit. The rigid benzimidazole-carboxylate ligand maintains the cluster's symmetry while providing hydro
