摘要

Two novel complexes based on 2-aminopyridine and polyoxometalates (POMs) formulated as (C₅H₇N₂)₆-[PMo ₁₁^VMo^VIO₄₀ (V^IVO) ₄]·H₂O (1) and (C₅H₇N ₂)₁₆[P₂W₁₈O_61.5] ₂ (2) were hydrothermally synthesized and structurally characterized by elemental analysis, ICP, IR, UV-Vis, TG, ESR and single crystal X-ray diffraction methods. Complex 1 consists of a novel terra-capped Keggin POMs, [PMo₁₁^VMo^VIO₄₀(V^IVO) ₄]^6-, in which four [V^IVO₅] square pyramids cap the equatorial positions of Keggin core [PMo₁₁ ^VMo^VIO₄₀]^14-, linked together with six protonated 2-aminopyridine via hydrogen bonding interactions. Dawson and lacunary Dawson POMs, [P₂W₁₈O₆₂]^6- and [P₂W₁₇O₆₁]^10- coexist in complex 2, they link together with sixteen protonated 2-aminopyridine via hydrogen bonding interactions. Complex 2 exhibits photochromic property.
