Synthesis and Crystal Structure of A Three-dimensional Coordination Polymer [Co(pda)(SCN)(H2O)]n [pda=3-(3-pyridyl)acrylic acid]

以CoCl2、3-(3-吡啶基)丙烯酸(pda)和KSCN为原料,在水热反应条件下,合成了一种三维配位聚合物[Co(pda)(SCN)(H2O)]n晶体,对其进行了元素分析、红外光谱表征、X射线单晶衍射测定和热重分析.该配位聚合物属三斜晶系,P-1空间群,晶胞参数为a=0.7309(5)nm,b=0.8799(6)nm,c=0.9634(6)nm,α=68.128(10)°,β=73.241(11)°,γ=71.218(12)°,V=0.5343(6)nm3,Z=2,dc=1.760g/cm3,μ=1.792mm-1,F(000)＝268,R1=0.0450, wR2= 0.1035.X射线单晶衍射显示形成一个三维的网络结构.
