Reactivity of the Asymmetric Wells-Dawson Ion: Lanthanide-Containing 34-Tungsto-2-Phosphates [Ln(P(H₄)W₁₇O₆₁)₂]^19- (Ln = La³⁺, Ce³⁺, Eu³⁺, Gd³⁺, Yb³⁺, Lu³⁺, Y³⁺).

ABSTRACT: We report on the synthesis of the lanthanide-containing 17-tungsto-1-phosphates [Ln(P(H₄)W₁₇O₆₁)₂]^19- (Ln = La³⁺, Ce³⁺, Eu³⁺, Gd³⁺, Yb³⁺, Lu³⁺, Y³⁺), comprising a lanthanide ion connecting two [P(H₄)W₁₇O₆₁]^11- units in a syn-configuration. The compounds were characterized in the solid state by IR, powder XRD, and TGA, and in solution by ³¹P and ¹⁸³W NMR. Alternating current magnetic susceptibility investigations revealed the Ce³⁺ and Yb³⁺ analogues to be single-molecule magnets (SMM), which was further corroborated by sub-kelvin temperature μSQUID studies.
