以双(4-吡啶-4-苯基)胺(BPPA)和4,4-(六氟)双(苯甲酸)(H2hfipbb)或对苯二甲酸(p-H2bdc)为配体,采用溶剂热法与M(NO3)2·6H2O(M=Co、Zn)组装合成了2个新的配合物{[Co2(BPPA)(hfipbb)2·(H2O)3]·6H2O}n(1)、{[Zn2(BPPA)2(p-bdc)2]·H2O·DMF}n(2),利用元素分析、X射线粉末衍射(PXRD)、红外光谱等手段分别对它们进行了表征,并用X射线单晶衍射仪测定了配合物的单晶结构。X射线单晶衍射测定结果表明:配合物1和2均为二维结构。配合物1具有新的拓扑结构。配合物2的二维结构又可以组成三维框架结构。配合物1为正交晶系,Pnna空间群,a=2.640 9(2)nm,b=1.715 78(13)nm,c=1.504 11(11)nm,V=6.8154(9)nm3,Z=4,μ=0.571 mm-1,F(000)=2 592,Dc=1.245 g·cm-3,Mr=1 383.76,R1=0.066 6,w R2=0.208 9(I>2σ(I));配合物2为单斜晶系,C2/c空间群,a=2.796 70(9)nm,b=1.814 82(6)nm,c=2.303 13(7)nm,β=102.136 0(10)°,V=11.428 3(6)nm3,Z=8,μ=0.906 mm-1,F(000)=4 944,Dc=1.391 g·cm-3,Mr=1 196.85,R1=0.039 8,w R2=0.106 4(I>2σ(I))。此外,热重分析表明配合物1和2均具有良好的热稳定性。
(BPPA) and 4,4- (hexafluoro) bis (benzoic acid) (H2hfipbb) or terephthalic acid (p-H2bdc) Two new complexes {[Co2 (BPPA) (hfipbb) 2 · (H2O) 3] · 6H2O} n (1) were synthesized by the method of M (NO3) 2 · 6H2O (M = Co, Zn) [Zn2 (BPPA) 2 (p-bdc) 2] · H2O · DMF} n (2) were synthesized and characterized by elemental analysis, XRD and IR spectroscopy. The crystal structure of the complex was determined by crystal diffractometer. X-ray single crystal diffraction measurement results show that: complexes 1 and 2 are two-dimensional structure. Complex 1 has a new topology. The two-dimensional structure of the complex 2 can form a three-dimensional framework structure. The complex 1 is orthorhombic and the space group of Pnna has a = 2.640 9 (2) nm, b = 1.715 78 (13) nm, c = 1.504 11 (11) nm and V = 6.8154 (9) , Μ = 0.571 mm-1, F (000) = 2 592, Dc = 1.245 g · cm -3, Mr = 1 383.76, R1 = 0.066 6, w R2 = 0.208 9 (I> 2σ (I)); The complex 2 is monoclinic with space group C2 / c, a = 2.796 70 (9) nm, b = 1.814 82 (6) nm and c = 2.303 13 , V = 11.4283 (6) nm3, Z = 8, μ = 0.906 mm-1, F (000) = 4 944, Dc = 1.391 g · cm-3, Mr = 1 196.85, R1 = 0.039 8, = 0.106 4 (I> 2σ (I)). In addition, thermogravimetric analysis showed that both complexes 1 and 2 have good thermal stability.
