摘要: 在水热体系中以二乙烯三胺为模板剂合成了结构新颖的亚磷酸锌化合物Zn(DETA)Zn2(HPO3)3.单晶X射线衍射分析结果表明,该化合物属正交晶系,Cmca空间群,晶胞参数a=1.889 25(1)nm,b=1.001 04(5)nm,c=1.630 32(8)nm,β=90°,V=3.083 3(3)nm3,Z=4,DC=1.162 Mg.m-3,最终因子R1[I>2σ(I)]=0.068 5,wR2[I>2σ(I)]=0.160 5.该化合物的结构中含有{ZnO4},{ZnO2N3}和{HPO3}基本结构单元,其中{ZnO4}和{HPO3}通过桥氧原子共顶点相互交替连接形成具有4-,8-和12-元环的无限延伸的二维层.有趣的是,{ZnO2N3}结构单元以二聚体形式{ZnODETA}2悬挂在12-元环孔道中,这种结构在亚磷酸锌中鲜有报道.

Abstract: A novel 2D layer zinc phosphite compound Zn(DETA)Zn2(HPO3)3 was hydrothermally synthesized.Single crystal X-ray diffraction reveals that the compound crystallized in the orthorhombic space group,Cmca,with a=1.889 25(1) nm,b=1.001 04(6) nm,c=1.630 32(8) nm,β=90°,V=3.083 3(3) nm3,Z=4,DC=1.162 Mg·m-3, R10.067 9 and wR20.158 3.The structure consists of {ZnO4},{ZnO2N3} and {HPO3} basic structural units.The vertexsharing {ZnO4} and {HPO3} units are connected forming an infinite 2D layer with four-,eight-and twelve-membered rings.It is very interesting that {ZnODETA}2 dinuclear units are grafted in the twelve-membered ring channels.
