摘要
在水热条件下,合成了双晶胞铜配位聚合物[Cu(bipy)2SO4]2.2SO4(bipy=2,2′-联吡啶).对该化合物进行了红外光谱和单晶X射线衍射表征.结果表明:该化合物属于三斜晶系,P1空间群;晶胞参数a=0.7390(2)nm,b=1.1294(5)nm,c=1.4960(2)nm,α=110.1830(6)°,β=96.5160(4)°,γ=99.8380(4)°,V=1.1345(4)nm3,Z=2,R1=0.0886,wR2=0.1583.在[Cu(bipy)2SO4]2.2SO4中,bipy通过2个N原子与Cu2+配位并通过SO24-连接形成无限延伸的一维链状结构,一维链状结构进一步通过相邻的bipy环的π-π相互作用连接形成无限延伸的二维层状结构.
A novel double-cell copper coordination polymers [Cu(bipy)2SO4]2 2SO4 has been synthesized taking sulfate anion under hydrothermal condition and characterized by means of infrared spectra and single crystal X-ray diffraction.Bipy forms double-cell structure by the fact that two N atoms and one Cu(Ⅱ) ions match place.Pass sulfate anion chain,π-π bond interacts forming one-dimensional and two-dimensional infinitely extended layer structure.The crystallographic data are crystallized in triclinic with group P1,a=0.739 0(2) nm,b=1.129 4(5) nm,c=1.496 0(2) nm,α=110.183 0(6)°,β=96.516 0(4)°,γ=99.838 0(4)°,V=1.134 5(4) nm3,Z=9,R1=0.088 6,wR2=0.158 3.
