Abstract

Abstract: The synthesis and structure of a new, highly augmented {Cu2 }‐"paddlewheel"‐based metal–organic framework (MOF) that is stabilized by tritopic benzoate ligands is reported. The structure adopts an uncommon, less symmetrical, (3, 4)‐connected net topology and represents a rare framework isomer of the extensively studied {Cu2 }‐based pto and tbo analogues related to the purely inorganic, solid‐state structures of platinum oxide or the twisted boracite. The concomitant formation of three isomeric forms by using {Cu}2 ‐"paddlewheel" complexes and a single triangular, trifunctional ligand is unique and stems from the rotational flexibility of the benzoate moieties. Computational analyses support the structural studies and underline that this observed net topology can give rise to an exceptionally high surface area (greater than 3500 m 2 /g) despite the triple‐interpenetrated nature of the compound.
