在碱性水溶液中获得了组分为Na_4H[Cu(H_2TeO_6)_2]·17H_2O的晶体配合物。用X-射线衍射法测定了单晶结构,晶体属三斜晶系,空间群 P_1,a=0.5939(2)nm,b=0.8957(3)nm,c=1.2555(3)nm,α=98.49(2)°,β=98.98(2)°,γ=93.94(2)°,V=0.6495(3)nm~3,M=913.7,Dc=2.34s/cm~3,Z=1.晶体中二个畸变的TeO_4(OH)_2八面体与中心Cu(Ⅲ)离子螯合,构成属准D_(2h)点群对称的CuO_4平面,Cu—O键长分别为0.1830nm和0.1844nm。 配合物溶液的紫外吸收光谱,于270nm和405nm处有两个强的配体至金属电荷转移谱带。
The crystal complex of Na_4H [Cu (H_2TeO_6) _2] · 17H_2O was obtained in alkaline aqueous solution. The crystal structure of triclinic system was determined by X-ray diffraction. The space group P_1, a = 0.5939 (2) nm, b = 0.8957 (3) nm, c = (2) °, β = 98.98 (2) °, γ = 93.94 (2) °, V = 0.6495 (3) nm ~ 3, M = 913.7, Dc = 2.34 s / cm ~ 3, and Z = The two distorted TeO_4 (OH) 2 octahedra are chelated to the central Cu (Ⅲ) ion to form a CuO_4 plane with a quasi D_ (2h) point group symmetry. The CuO bond lengths are 0.1830 nm and 0.1844 nm, respectively. The UV spectrum of the complex solution shows two strong ligand to metal charge transfer bands at 270 nm and 405 nm.
