| 摘要: 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。 |

| Abstract: A new Sm3+ complex [Sm2(BTA)3·(H2O)10]·5H2O (1) (H2BTA=5, 5-bis(1H-tetrazoly)amine, CAS No. 127661-01-2) was synthesized by the hydrothermal reaction of SmCl3·6H2O and bis(tetrazoly)amine, and characterized by X-ray diffraction and elemental analysis. The crystal of 1 is triclinic with space group P1. In 1, two Sm3+ ions are coordinated to the chelated N atoms of BTA anions and water molecules to give two different mononuclear units with a distorted tetragonal antiprism structure. A 3D supermolecular structure is formed by three different intermolecular hydrogen bonding interactions of O-H…N, O-H…O and N-H…N in this complex. CCDC: 894688 |
