利用碘化铅和1,10-邻菲啉反应,合成了一维链状加合物PbI2(1,10-phen)。通过元素分析和红外光谱对其结构进行了表征。用X-射线单晶衍射测定了该加合物的晶体结构。结果表明,该配合物的晶体属单斜晶系,空间群C2/c,晶胞参数:a=16.460(5),b=11.161(4),c=8.292(3),β=103.335(4)°,Z=4,Dc=2.873Mg/m3,V=1482.1(8)3,μ=15.529mm-1,F(000)=1128,R1=0.0353,wR2=0.0712。在该配合物中,铅原子为六配位的畸变的八面体构型。并且通过碘原子的桥联作用形成一维链状聚合物。
One-dimensional chain adduct PbI2 (1,10-phen) was synthesized by the reaction of lead iodide with 1,10-phenanthroline. Its structure was characterized by elemental analysis and infrared spectroscopy. The crystal structure of the adduct was determined by X-ray single crystal diffraction. The results show that the crystal of the complex belongs to the monoclinic system with space group C2 / c. The unit cell parameters are a = 16.460 (5), b = 11.161 (4), c = 8.292 ) °, Z = 4, Dc = 2.873 Mg / m3, V = 1482.1 (8) 3, μ = 15.529 mm -1, F (000) = 1128, R1 = 0.0353, wR2 = 0.0712. In this complex, the lead atom is a hexacoordinated distorted octahedral configuration. And a one-dimensional chain polymer is formed by the bridging action of iodine atoms.
