N2 - Three types of serine-decorated rare- earth-containing arsenotungstate [H2N(CH3)2]6NaH[RE2W4O10(H2O)8(Ser)2(B-α-AsW9O33)2]⋅30 H2O (RE3+=Eu3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, Tm3+, Yb3+, and Y3+; 1), [H2N(CH3)2]6Na6−xRExH4−2 x[RE4W8O19(H2O)10+y(OH)2(Ser)2(B-α-AsW9O33)4]⋅n H2O (RE3+=Tb3+, x=1, y=2, n=36; RE3+=Dy3+, Ho3+, Er3+, Yb3+, Y3+, x=0, y=0, n=38; RE3+= Tm3+, x=1, y=0, n=38; Ser=serine; 2), and [H2N(CH3)2]6−2 xNa2+3 xRExH10−6 x+y[RE4W8O19(H2O)8(OH)2(Ser)4(B-α-AsW9O33)4]⋅Cly⋅n H2O (RE3+=Ce3+, Pr3+, x=1, y=0, n=65; RE3+=Nd3+, Sm3+, x=0, y=0, n=65; RE3+=Eu3+, Gd3+, x=1, y=2, n=45; 3) were synthesized with the participation of the organic solubilizers dimethylamine hydrochloride and l-serine and were structurally characterized. The use of different amounts of rare-earth salts results in the structural transformation from dimerization to tetramerization of types 1–3. Type 1 is a dimeric sandwich-type assembly of a dual-Ser-participating [RE2W4O10(H2O)8(Ser)2]10+entity sandwiched by two [B-α-AsW9O33]9−moieties, whereas types 2 and 3 have a tetrameric square structure formed by four [B-α-AsW9O33]9−moieties that anchor a dual/tetra- Ser-participating [RE4W8O19(H2O)10+y(OH)2(Ser)2]20+or [RE4W8O19(H2O)8(OH)2(Ser)4]20+core. The solid-state luminescence properties and lifetime–decay behaviors of these compounds were investigated. The chromaticity coordinates, dominant wavelengths, color purities, and correlated color temperatures were also calculated.
