چکیده
The deliberate synthesis of the Keplerate [K(20) subset{(W)W(5)O(21)(SO(4))}(12)(VO)(30)(SO(4))(H(2)O)(63)](18-) with 20 pores all closed by K(+) in a supramolecular fashion proves that it is possible to follow new routes in polyoxotungstate chemistry based on pentagonal {(W)W(5)}-type units and to tune magnetic exchange couplings in {(M)M(5)}(12)M'(30) type Keplerates.

MnTiO3-Zeolite-Y nanocomposites were synthesized with 5-10-20% (w/w) of MnTiO3 by stearic acid gel method. Then, the gels were calcined at 900 °C for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. Also, the presence of rhombohedral phase of MnTiO3 in Zeolite-Y matrix was confirmed by XRD, SEM, EDX and BET. The VSM results showed t...

Addition of [Mo(2)(V)O(2)(μ-O)(μ-S)(aq)](2+) linker-type units to a solution/dynamic library containing tungstates results via the formation of the complementary pentagonal {(W)W(5)} units logically in the self-assembly of a mixed oxide/sulphide {W(VI)(72)Mo(V)(60)}-type Keplerate, thereby demonstrating the ability to tune the capsule's skeletal softness (the (μ-O)(2) and (μ-S)(2) scenarios are...
