Synthesis and crystal structure of one-dimensional chain adduct:PbI_2(1,10-phen)

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。
