Synthesis and Characterization of 8-Yttrium(III)-Containing 81-Tungsto-8-Arsenate(III), [Y8(CH3COO)(H2O)18(As2W19O68)4(W2O6)2(WO4)]43−

Abstract

Abstract:The 8-yttrium(III)-containing 81-tungsto-8-arsenate(III) [Y8(CH3COO)(H2O)18(As2W19O68)4(W2O6)2(WO4)] 43− (1) has been synthesized in a one-pot reaction of yttrium(III) ions with [B-α-AsW9O33] 9− in 1 M NaOAc/HOAc buffer at pH 4.8.Polyanion 1 is composed of four {As2W19O68} units, two {W2O10} fragments, one {WO6} group, and eight Y III ions. The hydrated cesium-sodium salt of 1 (CsNa-1) was characterized in the solid-state by single-crystal XRD, FT-IR spectroscopy, thermogravimetric and elemental analyses.

Synthesis, structure and electrochemical characterization of an isopolytungstate (W4O16) held by MnII anchors within a superlacunary crown heteropolyanion {P8W48}

“…[1][2][3][4][5][6] Lacunary POM ligands are versatile all-inorganic molecular precursors for the construction of molecule-based materials. Meanwhile, the structural varieties and functionalities of these materials could be tuned by the incorporation of different transition metal (TM) ions, [6][7][8][9] rare earth (RE) metal cations, [10][11][12][13][14][15][16] and mixed TM-RE metal centers [17][18][19][20] within the POM framework. 25− in 2005 drew attention to the fact that a cyclic anionic POM {P 8 W 48 } is an excellent superlacunary "molecular container" system for "cluster within cluster" assemblies.…”

Syntheses, and Crystal Structures of YIII Containing Di‐Metal Substituted 1,5 Isomers of Heterometallic Tungstophosphate Nanoclusters: [Y{PM2W10O38(H2O)2}2]11– (M=CoII and ZnII)

“…[24] It is not stable in aqueous solution which further leads to the formation of tetra-metallic species [M 4 (OH 2 ) 2 (PW 9 O 34 ) 2 ]. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] This reaction was carried out in the presence of Y III ion, resulting in the formation of sandwiched complex. Y III ion is sandwich by two units of dimetal substituted tungstophosphate (Figure 1).…”

“…[18] Kortz et al have also reported 8-Yttrium containing 81-Tungsto-8-Arsenate following a one-pot synthetic procedure in 2015. [19] After several reported yttrium-substituted compounds, Hussain et al in 2016 have also synthesized yttrium containing dimeric and tetrameric Keggin-type tungstophosphate and studied its catalytic activity for alcohol oxidation. [20] In 2016, Hussain [21] Recently, in 2018, Hussain et al have also reported a carbonate-encapsulated yttrium (III)containing tungstoarsenate (III) along with two yttrium and ytterbium containing tungstogermanates.…”

The Fascination of Polyoxometalate Chemistry

“…Next, the up-coming field of lanthanide substituted polyoxometalates is represented by the contributions of Ulrich Kortz and co-workers [3] and of Israël M. Mbomekallé and co-workers [4]. Ulrich Kortz and his team present the synthesis and characterization of a new polynuclear lanthanidesubstituted polyoxometalate with the formula Y8(CH3COO)(H2O)18(As2W19O68)4(W2O6)2(WO4) 43− .…”
