【摘要】以二甲基-2,2′-二羟基-1,1′联萘-3,3′-二羧基酯与硝酸镉的组装得到了一个稳定的二维配位化合物[Cd3L2(py)4]n.通过单晶X-射线衍射测试、红外光谱和元素分析对化合物进行了表征.化合物1为单斜晶系,P2/c空间群,a=12.678 1(4),b=12.761 4(4),c=16.887 7(5),β=97.24°,V=2 252.71(1)3,Z=2,R1=0.054 1,GOF=1.068.更多还原

【Abstract】 Assembly of a flexible bipyridyl ligand with Cd(Ⅱ) center gave rise to a two-dimensional complexes [Cd3L2(py)4]n,which was characterized by single-crystal X-ray diffraction.The polymer crystallizes in the monoclinic system,space group P2/c with unit cell parameters:a = 12.678 1(4),b = 12.761 4(4),c = 16.887 7(5) ,β =97.24°,V = 2 252.71(1)3,Z = 2,C64H42 Cd3 N4 O12,Mr =1 340.264,Dc = 1.255 g/cm3,F(000) = 1 384,μ(MoKα) = 1.237 mm-1.The final R and wR are 0.054 1 and 0.118 2 for 4 781 observed reflections with I≥2σ(I).更多还原
