通过水热合成的方法得到了一个新的化合物[Pb2(L1)2(L2)2],并对该化合物进行了元素分析、红外、热重和单晶X-射线表征(H2L1为丁二羧酸阴离子,L2为邻菲啰啉衍生物)。该化合物属于单斜晶系,空间群P21/c,晶胞参数:a=0.795 40(10)nm,b=2.649 0(3)nm,c=1.996 9(2)nm,β=99.784(2)°,V=4.1463(9)nm3,Z=4,R=0.038 0,wR=0.084 5。在该化合物中,丁二酸阴离子连接着铅原子形成一维链状结构。此外,链与链之间的π-π相互作用使一维链形成了三维超分子结构。最后,N-H…29…29O氢键进一步地稳定了此三维超分子结构。
A new compound [Pb2 (L1) 2 (L2) 2] was synthesized by hydrothermal method and characterized by elemental analysis, IR, TG and single crystal X-ray characterization Acid anions, L2 phenanthroline derivatives). The compound belongs to the monoclinic system with space group P21 / c, with the unit cell parameters of a = 0.795 40 (10) nm, b = 2.649 0 (3) nm, c = ) °, V = 4.1463 (9) nm3, Z = 4, R = 0.038 0, wR = 0.084 5. In this compound, succinic acid anions are attached to lead atoms to form a one-dimensional chain structure. In addition, the π-π interaction between chains makes the one-dimensional chains form a three-dimensional supramolecular structure. Finally, N-H ... 29 ... 29O hydrogen bonds further stabilized this three-dimensional supramolecular structure.
