Abstract: Two novel organic–inorganic compounds based on tetrahexylammonium (THA) and tetraheptylammonium (THPA) ions and the Preyssler anion, [NaP₅W₃₀O₁₁₀]^14-, were synthesized and formulated as (THA)_7.7H_6.3[NaP₅W₃₀O₁₁₀] (A) and (THPA)_7.5 H_6.5[N aP₅W₃₀O₁₁₀] (B). The synthesized compounds were characterized by IR, UV, and TGA and used for the catalytic synthesis of 4-aminopyrazolo[3,4,-d]pyrimidine derivatives 2a-2d. Our findings showed efficient catalytic activities for A and B.
