This critical review presents a comprehensive study of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) towards construction and synthesis of metal-organic frameworks (MOFs). We describe the geometries of 131 SBUs, their connectivity and composition. This contribution presents a comprehensive list of the wide variety of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) in the construction and synthesis of metal-organic frameworks. The SBUs discussed here were obtained from a search of molecules and extended structures archived in the Cambridge Structure Database (CSD, version 5.28, January 2007) which included only crystals containing metal carboxylate linkages (241 references).

“…A similar copper tetramer was previously prepared using a hexanoate ligand system, though it is noted this complex possessed terminal urea ligands [26]. The hexanoate complex is comparable to 6, with a Cu-Cu distance of 2.5791 (5) Table 3 Selected bond lengths (Å ) and angles (8) (Cu-Cu: 2.575 Å´, CuÁ Á ÁCu 3.269 Å´) [29], and decanoate (Cu-Cu: 2.624 Å´, CuÁ Á ÁCu 3.365 Å´) [30].…”

“…[29][30][31] The paddle wheel binuclear metal clusters within M(bdc)(ted) 0.5 can be found in a large number of reported nanoframeworks materials with high microporosity, thermal stability, good sorption properties and other advanced functional properties such as magnetic property. [32][33][34][35][36][37] Using new pillaring or mixed ligands, it is possible to prepare a variety of functionalized and flexibly tuned 3D architectures by altering the nature of carboxylate and pillaring ligands. 31,38,39 We combine (i) in-situ infrared (IR) spectroscopy, (ii) ex-situ Raman spectroscopy, and (iii) powder X-ray diffraction to investigate the reaction of water molecules with the prototypical frameworks M(bdc)(ted) 0.5 with paddle-wheel type secondary building units (SBUs).…”

Instability of most prototypical metal organic frameworks (MOFs) in the presence of moisture is always a limitation for industrial scale development. In this work, we examine the dissociation mechanism of microporous paddle wheel frameworks M(bdc)(ted) 0.5 [M=Cu, Zn, Ni, Co; bdc= 1,4-benzenedicarboxylate; ted= triethylenediamine] in controlled humidity environments. Combined in-situ IR spectroscopy, Raman, and Powder x-ray diffraction measurements show that the stability and modification of isostructual M(bdc)(ted) 0.5 compounds upon exposure to water vapor critically depend on the central metal ion. A hydrolysis reaction of water molecules with Cu-O-C is observed in the case of Cu(bdc)(ted) 0.5 . Displacement reactions of ted linkers by water molecules are identified with Zn(bdc)(ted) 0.5 and Co(bdc)(ted) 0.5 . In contrast, . Ni(bdc)(ted) 0.5 is less susceptible to reaction with water vapors than the other three compounds. In addition, the condensation of water vapors into the framework is necessary to initiate the dissociation reaction. These findings, supported by supported by first principles theoretical van der Waals density functional (vdW-DF) calculations of overall reaction enthalpies, provide the necessary information for determining operation conditions of this class of MOFs with paddle wheel secondary building units and guidance for developing more robust units.
