摘要
本文通过水热法合成了一种3-吡啶甲酸(L=3-吡啶甲酸)和钴(Ⅱ)的配合物Co(L)2(H2O)4。通过元素分析,红外光谱,X-射线单晶衍射等对所合成的对3-吡啶钴的配合物进行了表征,结果表明该配位聚合物属于单斜晶系,C2/m空间群,晶胞参数为a=14.155 2(13),b=6.882 7(6),c=8.492 1(8),β=118.284 0(10)°,晶包体积V=728.57(11)nm3,Z=2,Mr=375.20,Dc=1.710,F(000)=386,μ=1.224 cm-1,R1=0.023 2,w R2=0.069 2。通过对其结构的分析,认为它是一种新的钴(Ⅱ)的配合物,钴(Ⅱ)与配体分子上的N和水分子中的O形成了六配位结构。
3- pyridinecarboxylic acid is very wide used ligand. A novel compound Co( L)2 (H2O)4 is synthesized and its structure are determined by single - crystal X - ray diffraction in the paper. The crystal belongs to monoclinic, space group c^2/m witha= 14. 155 2(13), b = 6.882 7(6),c = 8.492 1(8),13 = 118.2840(10)°A3,V = 728.57(11) , Z= 2, Mr = 375.20, Dc = 1.710/m^3, F(000) = 386, μ = 1.224 mm^-1, R1 = 0.0232, w R2 = 0.0692, Through the analysis of the structure of it , we know that it is a new complexes of cobalt.
