在含有HF的体系中,用乙二胺作模板剂,通过水热方法合成了一个新的三维亚磷酸铟[In4(HPO3)7(H2O)3](NH3CH2CH2NH3)(H2O),并对其进行了红外光谱、热重、ICP和CHN元素分析等表征.单晶X射线衍射分析结果表明,该化合物属于三方晶系,P3空间群,晶胞参数a=1.37883(7)nm,c=0.93450(9)nm,V=1.53862(2)nm3,Z=2,Dc=2.489Mg/m3,最终一致性因子R1[I>2σ(I)]=0.0526,wR2[I>2σ(I)]=0.1328,GOF=1.082.其结构中的InO6八面体、InO5(H2O)八面体和HPO3假四面体通过O原子共顶点连接,分别沿a,b轴方向形成含有十二元环的交叉孔道,客体水分子和双质子化的乙二胺分子存在于孔道中.
In the HF-containing system, a new three-dimensional indium phosphite [In4 (HPO3) 7 (H2O) 3] (NH3CH2CH2NH3) (H2O) was synthesized by a hydrothermal method using ethylenediamine as a template and subjected to The results of single crystal X-ray diffraction analysis show that the compound belongs to the trigonal system with space group P3, a = 1.37883 (7) nm and c = 0.93450 The final concordance factor R1 [I> 2σ (I)] = 0.0526, wR2 [I> 2σ (I)] = 0.1328 , GOF = 1.082. The InO6 octahedron, InO5 (H2O) octahedron and HPO3 pseudotetrahedron in the structure are connected by the common apexes of O atoms, forming cross-holes with 12-membered rings along the a and b axes respectively. Molecules and di-protonated ethylenediamine molecules are present in the pores.
