Synthesis,Crystal Structure and Recognition of Pb^(2+) Ion of 2D Network Coordination Polymer [Co( btmb)_2(SCN)_2]_n

以联苯二苄三氮唑(btmb)为配体,在水热实验条件下与CoCl2反应,得到了一个新的二维网状配聚物[Co(btmb)2(SCN)2]n.X射线单晶衍射分析结果表明,该晶体属单斜晶系,空间群为C2/c.晶胞参数为:a=0.952 12(19)nm,b=1.414 7(3)nm,c=2.882 5(6)nm,α=90°,β=91.33(3)°,γ=90°.研究表明,该配聚物具有较好的Pb2+识别性能.

A new 2D network coordination polymer [Co（btmb） 2 （SCN）2] n was synthesized by the hydrothermal reaction of 4,4＇-bis （benzotriazole-1-ylmethyl） biphenyl （btmb） with CoCl2.X-ray diffraction technique revealed that the crystal belonged to monoclinic crystal system,C2/c space group,and its crystal cell parameterswere：a=0.952 12（19） nm,b=1.4147（3） nm,c=2.8825（6） nm,α=90°,β =91.33 （3）°,and γ=90°.It was revealed that the obtained coordination polymer could recognize the presence of Pb^2＋ ions by UV-Vis spectroscopy.
