摘要：

A supermolecular compound, {[8-hydroxyquinolineH](4)(4 +) center dot [SiW12O40](4 -)center dot 2H(2)O} was synthesized by hydrothermal reaction with silico-tungstic acid and 8-hydroxyquinoline. The crystal of the compound belongs to monoclinic system, space group P2(1)/n, with a=1.282 6(6) nm, b=2.2927(4) nm, c=2.0920(6) nm, beta=95.495(2)degrees, Z = 4, V=6.124 1(7) nm(3), D-c = 3.791 g(.)cm(-3), mu=22.568 mm(-1), F(000)=6 200, R-1=0.029 3, wR(2)=0.069 3, GOF=1.079. Supermolecular compound is composed of one SiW12O404- with Kegginstructure, four protonated cations of 8-hydroxyquinoline, two hydrones. Thermal analysis results showed that the anionic skeleton construction of heteropoly acid in compound decomposed approximately at 349.0 degrees C. CCDC: 622142.
