摘要
合成了一个具有三维骨架结构的无机 -有机杂化微孔材料Zn3(bpdc)3(4,4′ bpy)·DMF·2H2 O,并通过ICP和X射线单晶衍射分析等手段对其结构进行了表征.晶体属于正交晶系,Pbcn空间群,晶胞参数a =1.45 3 2 (3)nm,b =2.5 0 3 7(5 )nm,c=1.8184(4)nm,V =6.616(2 )nm3,Z =8,Dc=1.2 96g/cm3,Mr=64 5.5 8,μ =1.145mm-1,F(0 0 0)=2 65 6.最后的一致性因子为R =0.0 70 5,Rw =0.2 0 5 6.
Single crystal of Zn_3(bpdc)_3(4,4′-bpy)·DMF·2H_2O was synthesized under mild conditions and its crystal structure was determined using single crystal X-ray diffraction. The crystal structure was solved by direct method and refined by full-matrix least-square method. The crystal is orthorhombic and belongs to space group Pbcn with a=1.4532(3) nm, b=2.5037(5) nm, c=1.8184(4) nm, β=90°, V=6.616(2) nm 3, Z=8, D_c=1.296 g/cm 3, M_r=645.58, μ=1.145 mm -1, F(000)=2656, R=0.0705, Rw= 0.2056. The framework is built up from ZnO_4 tetrahedra and ZnO_6 octahedra, forming a three-dimensional framework.
