以双四唑胺(H2BTA)、氯化钐为原料,通过水热法合成了一个双四唑胺合钐配合物[Sm2(BTA)3.(H2O)10].5H2O(H2BTA=双四唑胺)。X-射线单晶衍射表征了这个配合物属于三斜晶系,P1空间群。在配合物中,两种不同的Sm3+离子与双四唑胺的2个螯合N原子和水分子配位形成2种八配位的四方反棱柱结构的单核配合物单元。在2种单核配合物单元和结晶水分子之间,存在着O-H…N,O-H…O和N-H…N 3种不同的氢键,形成三维超分子结构。
A novel bis-tetrazolium-samarium complex [Sm2 (BTA) 3 (H2O) 10] 5H2O (H2BTA = bistetrazole was synthesized from bis-tetrazolium (H2BTA) and samarium chloride amine). X-ray single crystal diffraction characterization of this complex belongs to triclinic, P1 space group. In the complex, two different Sm3 + ions coordinate with two chelator N atoms and water molecules of bisotiazideamine to form two kinds of eight-coordinated tetragonal anti-prism mononuclear complex units. There are three kinds of hydrogen bonds of O-H ... N, O-H ... O and N-H ... N between the two mononuclear complex units and the crystal water molecules to form a three-dimensional supramolecular structure.
