چکیده
Two hybrid assemblies (3 and 4) with two kind of nanoscaled cluster units, the spherical [Co(24)(TC4A)(6)(MO(4))(8)Cl(6)](2+) cation (1 and 2) and Keggin-type [PM(12)O(40)](3-) anion (M = Mo (1/3), W (2/4)), were solvothermally prepared and characterized, in which the spherical units are constructed by six Co(4)-p-tert-butylthiacalix[4]arene (Co(4)-TC4A) SBUs linked by eight MO(4) tetrahedrons and present the highest nuclearity bimetallic clusters capped by cailxarenes.

A {Co32} nanosphere supported by p-tert-butylthiacalix[4]arene.
Calixarene-capped Co(32) clusters are constructed by a sodalite Co(II)(24) cage and an encapsulated Co(III)(8) cube. The spherical units are arranged into three isomeric structures, two of which are stacked by the bcc lattices and the third of which is assembled by the cubic closest packing of the spherical units.
متن کاملConnecting theory with experiment to understand the initial nucleation steps of heteropolyoxometalate clusters.
A complimentary combination of Density Functional Theory (DFT) methodology and Electrospray Ionization-Mass Spectrometry (ESI-MS) has been utilized to increase our limited understanding of the first nucleation steps in the formation of the [XM(12)O(40)](n-) Keggin polyoxometalates (POMs) (where addenda metal atom M = W or Mo, and the heteroatom X = P or As). We postulate that the first key step...
متن کاملThe reaction of diethyl bromomalonate with p-tert-butylthia-calix[4]arene: an approach to asymmetrical derivatives.
New dissymmetric and asymmetric p-tert-butylthiacalix[4]arene derivatives were prepared as a result of the reaction of p-tert-butylthiacalix[4]arene with diethyl bromomalonate in the presence of different alkali metals (Cs, K and Na) in refluxing acetone for 7 days. The structures of the prepared compounds were investigated by IR, (1)H-NMR and MALDI-TOF mass spectroscopy.
متن کاملA comparative study between transition-metal-substituted Keggin-type tungstosilicates supported on anatase leaf as catalyst for synthesis of symmetrical disulfides
Transition-metal-substituted (TMS) polyoxometalates of the general formula [SiW9M3O39], (where M = first row transition metal), has been synthesized and supported on anatase by sol–gel method under oil-bath condition. The tetrabutylammonium (TBA) salts of the Keggin-type polyoxotungstates [SiW9M3O39], (M = VII, CrII, MnII, FeII CoII and NiII), proved to be green, reusable, and ...
متن کاملp-tert-Butylthiacalix[4]arenes functionalized by N-(4’-nitrophenyl)acetamide and N,N-diethylacetamide fragments: synthesis and binding of anionic guests
New p-tert-butylthiacalix[4]arenes, which are mono-, 1,2-di- and tetrasubstituted at the lower rim containing N-(4'-nitrophenyl)acetamide and N,N-diethylacetamide groups in cone and partial cone conformations have been synthesized. Their complexation ability towards a number of tetrabutylammonium salts n-Bu4NX (X = F-, Cl-, Br-, I-, CH3CO2-, H2PO4-, NO3-) was studied by UV spectroscopy. The eff...
