“…2 and 3 are stable in air and the good agreement between powder X-ray diffraction (PXRD) patterns for the as-synthesized samples and the simulated ones based on single-crystal data indicate the phase purities of 2 and 3 ( Figure S11, S12). [15] These results are consistent with their single-crystal structural analyses. 3 is only stable at temperatures lower than 220 8 8C, as evidenced by the variable-temperature PXRD patterns ( Figure S12), which further confirms that the framework with the diamondoid topology is more stable than the 2D structure.I nt he IR spectra of 1-3 ( Figure S14), the characteristic vibrational bands of Anderson-type anions for the terminal Mo=Ounits and the bridging Mo-O-Mo groups are located at 840-980 cm À1 and 620-730 cm À1 , [7g] respectively.…”

A new approach to prepare heterometallic cluster organic frameworks has been developed. The method was employed to link Anderson-type polyoxometalate (POM) clusters and transition-metal clusters by using a designed rigid tris(alkoxo) ligand containing a pyridyl group to form a three-fold interpenetrated anionic diamondoid structure and a 2D anionic layer, respectively. This technique facilitates the integration of the unique inherent properties of Anderson-type POM clusters and cuprous iodide clusters into one cluster organic framework.

“…25 This is mainly originated from two major disadvantages, which are their low stability and small pore size owing to the frequent presence of interpenetration. Thus, constructing purely inorganic microporous frameworks from diverse POM units joined by inorganic linkers provides a promising way to achieve new types of porous materials possessing both stability and versatility.…”

Four new architectures containing [Co 2 Mo 10 H 4 O 38 ] 6-polyoxoanion, [Ln(H 2 O) 7 ][Ln(H 2 O) 5 ][Co 2 Mo 10 H 4 O 38 ]·5H 2 O (Ln = Gd 1; Tb 2), and (NH 4 ) 3 [Ln(H 2 O) 6 ][Co 2 Mo 10 H 4 O 38 ]·6H 2 O (Ln = Gd 3; Tb 4) have been synthesized at different temperatures and characterized by elemental analysis, IR and Raman spectroscopy, TG analysis, powder X-ray diffraction and single crystal X-ray diffraction. Isostructural compounds 1 and 2 obtained at the higher temperature (85 o C), are built up of Evans-Showell-type polyoxoanions [Co 2 Mo 10 H 4 O 38 ] 6-respectively linked by Gd 3+ or Tb 3+ cations to form a 3D racemic framework with 1D zigzag channels. From the topological point of view, the 3D net is a rare binodal 4-connected SrAl 2 (sra) topology. As far as we know, compounds 1 and 2 represent the first examples of 3D architectures based on Evans-Showell-type polyoxometalate. Interestingly, the stable 3D microporous compounds exhibit selective adsorption ability: adsorbing water and methanol, as well as excellent photocatalytic activity for organic dye degradation under visible light irradiation. When the reaction temperature was decreased to room temperature (25 o C), two chiral species 3 and 4 were obtained, with a mono-supporting structure composed of one [Co 2 Mo 10 H 4 O 38 ] 6-polyoxoanion and one [Ln(H 2 O) 6 ] 3+ unit. These chiral mono-supporting motifs can be connected by strong hydrogen-bonding interactions to form a 3D chiral supramolecular architecture. They crystallize in the chiral space group P2 1 , as conglomerates of two enantiomerically pure crystals. Their absolute configurations were determined by the Flack parameters and solid state circular dichroism spectroscopy.

“…Generally, the metalorganic macrocycle possesses positive charge, and thus it needs a counteranion to keep charge balance. Polyoxometalates (POMs), a unique class of anionic clusters, can be used not only as counteranions but also as templates that are conducive to the formation of macrocyclic compounds [9][10][11][12][13][14][15][16][17][18][19]. Furthermore, such POM-based macrocyclic compounds could combine the advantages of both the POMs and the macrocycles and open up new possibilities in the pursuit of multifunctional materials with designed functional properties and aesthetic topological structures [6,8,19].…”

A hybrid compound, [Cu I 4 (bpmb) 4 ][PW VI 11 W V O 40 ] (1) (bpmb = 1,4-bis(pyrazol-1-ylmethyl)benzene), has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction analysis, infrared spectroscopy, elemental analyses and powder X-ray diffraction. In compound 1 crown-like [Cu 4 (bpmb) 4 ] 4+ macrocycles templated by Keggin-type [PW VI 11 W V O 40 ] 4− polyanions (abbreviated PW 12 ) exist. Supramolecular layers are formed by intermolecular hydrogen bonding interactions of discrete crown-like [Cu 4 (bpmb) 4 ] 4+ macrocycles and [PW VI 11 W V O 40 ] 4− polyanions. The electrochemical and luminescence properties of compound 1 were investigated.
