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.
Under hydrothermal conditions, the binary coordination polymer [Cu (bipy) 2SO4] 2.2SO4 (bipy = 2,2’-bipyridyl) was synthesized and characterized by FTIR and single crystal X-ray diffraction The results show that the compound belongs to the triclinic system with P1 space group. The unit cell parameters a = 0.7390 (2) nm, b = 1.1294 (5) nm, c = 1.4960 (2) nm, °, β = 96.5160 (4) °, γ = 99.8380 (4) °, V = 1.1345 (4) nm3, Z = 2, R1 = 0.0886 and wR2 = 0.1583. In [Cu (bipy) bipy forms an infinitely extended one-dimensional chain structure by two N atoms coordinated with Cu2 + and connected by SO24-linkage. The one-dimensional chain structure is further connected by the π-π interaction of the adjacent bipy rings to form an infinitely extended two-dimensional Layered structure.
