Paddle‐Wheel Zinc Carboxylate Clusters as Building Units for Metal‐Organic Frameworks

Abstract: Growth of interest to a field of materials chemistry such as the metal‐organic frameworks (MOFs) demands the comprehensible surveying of new results, and the reviews systematizing and highlighting one or another trend in the MOF research appear periodically. Structural peculiarities of coordination polymers constructed by zinc paddle‐wheel clusters and the investigation of their microporosity are reviewed in detail to emphasize those features of the materials, which are interesting both for the pure and applie… Show more

“…Structural recovery upon desolvation/resolvation cycles is not uncommon in MOF chemistry. 18 A survey of the literature indicates that Zn forms a number of common SBUs with carboxylate ligands, including three-and 15 four-bladed dinuclear paddlewheels, 19 Relatively few MOFs comprised of NHC ligands have been assessed for their catalytic performance. 9 Accordingly, we sought to investigate the potential of 1 to activate CO 2 via hydroboration.…”

“…This occurs when the axial group is a water ligand 5 but N donors favour a square pyramidal (SQP) structure. 6 However, the TBP and SQP coordination geometries have similar energies (c.f. the Berry pseudorotation) and the transition from TBP to SQP or vice versa is relatively easy.…”

“…17 Em outros, há formação de um grupamento de átomos metálicos (cluster). Uma das mais comuns é a chamada "paddle-wheel" (haste-roda), representada na Figura 1A, onde dois átomos metálicos estão ligados a quatro grupos carboxí-licos na configuração syn-syn, 18 com os dois átomos de oxigênio do mesmo grupo carboxílico fazendo uma espécie de ponte com os dois átomos metálicos. Outras SBUs usuais são a unidade básica de acetato de zinco octaédrica e o trímero prisma trigonal com um átomo de oxigênio no centro.…”

“…O processo de auto-montagem acontece pela formação de ligações coordenadas entre o metal e o ligante, assim como ligações mais fracas do tipo van der Waals ou pontes de hidrogênio entre os componentes não metálicos. 18 É possível preparar uma série de compostos com a mesma topologia de rede, mas diferindo apenas na natureza e tamanho do ligante, formando uma série de compostos isoreticulares.…”
