采用水热法得到了一种新型有机化合物4,4’醚氧二苯甲酸(C28H20O10),并对其进行了元素分析,通过X-射线单晶衍射测定了该晶体结构,晶体属正交晶系,空间群Pbca;晶胞参数:a=14.8468(17)nm,b=5.7249(7)nm,c=27.481(3)nm,α=90°,β=90°,γ=90°;Z=4,V=2335.8(5)nm3,Dc=1.469mg.m-3,μ=0.113 mm-1,F(000)=1072,最终偏离因子R1=0.0681,wR2=0.0993。在实验的基础上,运用Gaussian 03程序,在6-31G(d)的基组水平上,采用HF与B3LYP两种方法对标题化合物进行了几何全优化,并对其成键情况及自然键轨道(NBO)进行了分析。
One new organic compound 4,4'-oxybis(benzoic acid) (C28H20010) has been obtain with the hydro- thermal synthesis method and characterized by X- ray diffraction study, elemental analysis. The single crystal X - ray diffraction study shows that the title compound crystallizes in orthorhombic system, space group Pbca. Crystal data of the compound : a=14.8468(17)nm,b=5.7249(7)nm,c=27.481(3)nm,α=90°,β=90°,γ=90°;Z=4,V=2335.8(5)nm3,Dc=1.469mg.m-3,μ=0.113 mm-1,F(000)=1072, The final R1 and wR2 are 0.0681 and 0.0993. The theoretical investigation of the title compound as a structure unit was carried out by B3LYP/6 - 31G (d) and HF/6 -31G (d) methods, and the natural bond orbital were analyzed and atomic charges were also discussed.
