Polyoxometalates: Toward new materials

“…The resulting filtrate was kept for crystallization at room temperature. Block-type orange coloured-crystals were found in the solution after 10 …”

“…We have shown a chain-like extended structure based on an Anderson-type polyanion and a lanthanide cation linker in the compound [La(H 2 O) 7 Al(OH) 6 Mo 6 O 18 ] n · 4nH 2 O (1). 10 We succeeded in connecting this versatile building unit (Anderson-type POM anion) with a Cu(II)-complex ion, {Cu II (2,2 -bipy)(H 2 O) 2 } 2+ , to form a new type of chain in the compound [Cu II (2,2 - 11 A three-dimensional coordination polymer, Na 3 (H 2 O) 6 [Al(OH) 6 Mo 6 O 18 ] · 2H 2 O (3), was isolated when we cooked an acidified aqueous solution of AlCl 3 with sodium molybdate. 12,13 When we performed reactions between sodium vanadate, sodium tungstate and sodium dithionite in an aqueous ammonium acetate buffer, a one-dimensional heteropoly tungstovanadatecoordination polymer (NH 4 ) 4 (6) , and Ce 3+ (7) .…”

“…In this article, we have narrated an account of above mentioned seven compounds (1)(2)(3)(4)(5)(6)(7), that are already reported in last several years from our laboratory, [10][11][12][13][14][15] in terms of their syntheses and solid state structures. Finally, a new POV system [3-ampH] 6 …”

One‐, Two‐, and Three‐Dimensional Coordination Polymers Built from Large Mo36‐Polyoxometalate Anionic Units and Lanthanide Cations

“…[17] Organic linkers between the lanthanide centers can also be inserted, giving rise to new hybrid organic-inorganic polymeric frameworks. [18] Lanthanide complexes of [SiW 11 16 }]·nH 2 O [Ln = Tb, n = 42 (9); Ln = Dy, n = 43 (10), Ln = Ho, n = 46 (11), Ln = Er, n = 50 (12); Ln = Yb, n = 56 (13); Ln = Lu, n = 31 (14)]. 4 2-, NH 2 OH, and Nd 3+ .…”

Open‐Framework Polar Compounds: Synthesis and Characterization ofRare‐Earth Polyoxometalates (C6NO2H5)2[Ln(H2O)5(CrMo6H6O24)]·0.5H2O (Ln = Ce and La)

“…More recently, we and others, have prepared a few extended structures based on Anderson-type polyoxo anions, ranging from 1D chains to 2D networks. [19,20] The activity of the terminal oxygen atoms on the surface of this kind of POM makes it possible to form 3D covalent structures under an appropriate reaction condition. Furthermore, the employment of low-symmetry organic molecules or complexes as structure-directing agents is promising for the synthesis of new open-framework polar compounds.…”
