钨酸钠和2,6二甲基吡啶反应得到了分子组成为(Hdmpy)11H(H2W12O40)2·6H2O的化合物,用IR、UV光谱和单晶X射线衍射等手段进行了表征。晶体学数据如下单斜晶系,P21/c空间群,a=21628(4),b=21568(4),c=29183(6)nm,β=9292(3)°,V=13596(5)nm3,Z=4,Dc=3418Mg/m3,R=00565,wR=01008。晶体结构测定表明,质子化的2,6二甲基吡啶分子与偏钨酸阴离子间通过WOHN或WOHC的静电力和分子间作用力构造成无限二维空间网状结构。在05mol/L的NaClHCl溶液中,标题化合物的阴离子的循环伏安曲线表现为2步单电子还原过程。
The complex of (Hdmpy) 11H (H2W12O40) 2 · 6H2O with sodium tungstate and 2,6-dimethylpyridine was obtained and characterized by IR, UV spectra and single crystal X-ray diffraction. The crystallographic data are as follows: monoclinic, P21 / c space group a = 21628 (4) b = 21568 (4) c = 29183 (6) nm β = 9292 (3) ° V = 13596 ) nm3, Z = 4, Dc = 3418 Mg / m3, R = 00565, wR = 01008. The crystal structure determination shows that the protonated 2,6-dimethylpyridine molecule and the metatungungate anion are formed into an infinite two-dimensional network structure by the electrostatic force and intermolecular force of WOHN or WOHC. The cyclic voltammetry curve of the anions of the title compound appears as a two-step single electron reduction process in a 05 mol / L NaClHCl solution.
