Solvothermal Synthesis,Crystal Structure and Luminescence of a New Organic Amine Templated Samarium Sulfate

本文采用正丁醇与水的混合溶剂合成一种新的以有机胺为模板剂的硫酸钐盐:[C2N2H10]1.5[Sm(SO4)3(H2O)].2H2O(1),并通过X-射线衍射、红外、热重及元素分析对其进行了表征。该化合物晶体属于单斜晶系,P21/c空间群。其中a=0.65515(9)nm,b=2.648 3(4)nm,c=0.996 15(13)nm,β=104.067 0(10)°,V=1.676 5(4)nm3,Z=4。晶体结构分析显示化合物1中的波浪形层状结构由SmO9多面体与SO4多面体构成,同时非配位水与乙二胺通过氢键连接相邻的两个层。化合物1具有较强的荧光。

A new organic amine templated samarium sulfate [C2N2H10]1.5[Sm（SO4）3（H2O）]·2H2O 1 has been synthesized under solvothermal conditions by using a mixture of n-butanol and water as the solvent.The colorless block crystals structurally were characterized by single-crystal X-ray diffraction P21/c with crystal data a=0.655 15（9） nm,b=2.648 3（4） nm,c=0.996 15（13） nm,analysis,IR,TGA and ICP.Compound 1 crystallizes in the monoclinic space group β=104.067 0（10）°,V=1.676 5（4） nm3,Z=4.Crystal structure analysis shows that the waved layered framework of compound 1 is constructed from SmO9 polyhedra and sulfate groups,while non-coordination water molecules and ethylenediamine molecules link the adjacent layers by hydrogen bonds.Compound 1 indicates a strong luminescence upon the excitation.CCDC： 843656.
