摘要
水热合成了配合物[Cd2(bipy)4(NO3)3(H2O)]NO3(bipy=2,2’-联吡啶),并用单晶X-射线衍射测定了其晶体结构.配合物晶体属正交晶系,Pbca空间群,a=1.4361(3)nm,b=1.7215(2)nm,c=3.5099(5)nm,Z=8,Dc=1.708g/cm3,R1=0.0352,ωR2=0.0504.配合物中每一个镉离子均由两个2,2’-联吡啶的四个氮原子和两个氧原子配位构成变形八面体结构.
The complex, [Cd_2(bipy)_4(NO_3)_3(H_2O)]NO_3 (bipy=2,2'-bipyridine) has been hydrothermally synthesized and its crystal structure is determined by X-ray diffraction method. It crystallizes in orthorhombic system with space group Pbca. The crystal data are: a = 1.436 1(3) nm, b = 1.721 5(2) nm, c = 3.509 9(5) nm, z=8, Dc=1.708g/cm^3, R_1 = 0.035 2, ωR_2 = 0.050 4. In the title complex, each Cd(Ⅱ) ion presents a distorted octahedral geometry with the coordination of four nitrogen atoms from 2,2'-bipyridine and two oxygen atoms.
