本文通过溶剂热法合成出一种具有三维开放骨架结构的亚硝酸锌化合物{[Zn(NO2)3]-.H3O+.H2O}n(Zn1)。通过XRD、IR、拉曼光谱、TG和X射线单晶衍射对其结构进行了表征。X射线单晶衍射分析表明:该化合物属三方晶系,空间群为R-3c,晶胞参数a=b=c=0.8814(6)nm,α=β=γ=55.51(2)°,V=2.0394(2)nm3。Z=1 2,R1=0.0325,wR2=0.0829,GOF=1.077。Zn1的三维开放骨架结构由NO2-的O原子连接邻近的Zn原子构成,沿[100]和[110]方向上呈现八元环孔道。
A new three-dimensional open framework zinc nitrite {[ Zn (NO2 )3 ]·H3O^+·H2O}n (Zn1) was synthesized by solvothermal method. The products was characterized by X-ray powder diffraction (XRD), IR spectra, Raman spectra, TG analysis and structurally determined by single-crystal K-ray diffraction analysis. The results indicated that the compound crystallizes in the trigonal symmetry, space group R-3c, with a =b =c =0. 8814(6) nm, cg =/3 =y =55.51 (2)°, V=2. 0394(2) nm3, Z = 12, R1 =0. 0325, wR2 = 0. 0829, GOF = 1. 077. The adjacent Zn centers are linked with 0 from NO2 - to form 3-D structure of Znl containing 8-rings along [ 1001 and [ 110]direction, respectively.
