TL;DR: In this paper, the nano particles of (Bu 4 N) 7 H 3 [P 2 W 18 Cd 4 (Br) 2 O 68 ]-TiO 2 are small with a size of about 10nm.

TL;DR: A new polyoxometalate-based organic-inorganic platform has been designed for further facile derivatization and covalent attachment of organic linkers; this is exemplified by the grafting of a polypyridyl ligand.

TL;DR: Magnetic measurements performed on compounds 1 and 2 have shown the occurrence of antiferromagnetic interactions between the iron ions and have allowed the coupling constants between the magnetic centers to be determined.
Abstract: Two new insoluble transition metal substituted phosphotungstates, (C2N2H10)11[{(B-α-PW9O34)Fe3(OH)3}4(PO4)4Fe]·38H2O (1) and K4(C2N2H10)12[(α-PW10Fe2O39)4]·30H2O (2), have been isolated by the hydrothermal reaction of [A-α-PW9O34]9−, FeIII ions and ethylenediamine. Compound 1 has a tetrahedral symmetry and contains a Fe13 core built from the assembly of four FeIII trisubstituted [B-α-PW9O34]9− anions around a central disordered iron ion via four phosphato ligands. The anion in 2 can be described as a square of disubstituted [PW10O37]9− anions linked by FeIII–O–FeIII bridges. Magnetic measurements performed on 1 and 2 have shown the occurrence of antiferromagnetic interactions between the iron ions and have allowed the coupling constants between the magnetic centers to be determined.

TL;DR: Covalently linked polyoxometalate clusters are produced in the reaction of organic diisocyanates with [Bu4N]2[Mo6O19] as mentioned in this paper.
Abstract: Covalently linked polyoxometalate clusters are produced in the reaction of organic diisocyanates with [Bu4N]2[Mo6O19], suggesting the development of extended interconnected networks incorporating polyoxometalate ions.
