Palladium(II) Incorporation in the All‐Inorganic Cryptand [As₄W₄₀O₁₄₀]^28–: Synthesis and Structural Characterization of [Pd₂Na₂KAs₄W₄₀O₁₄₀(H₂O)]^21–

Abstract

The palladium(II)‐containing 40‐tungsto‐4‐arsenate(III) [Pd 2 Na 2 KAs 4 W 40 O 140 (H 2 O)] 21– ( 1a ) was synthesized by reaction of PdSO 4 with the cryptate heteropolyanion [As 4 W 40 O 140 ] 28– in potassium acetate buffer. The title compound was characterized by single‐crystal XRD, IR, TGA, and elemental analysis.
