摘　　要：利用水热工艺,选用{4-[3-(吡嗪-2-基)-1H-吡唑-1-基]}苯甲酸(缩写为HL)、CoCl2·6H2O和NH4VO3为起始原料,通过调控反应的p H及温度,我们成功地合成了一个新的2D层状配合物[Co(L)2(H2O)2]·3H2O。借助X-射线单晶衍射、元素分析、热重分析和IR光谱等测试手段对该化合物的结构进行了表征。结果表明该化合物属于C2/c空间群,单斜晶系,晶胞参数a=2.6164(5)nm,b=0.8401(5)nm,c=1.4286(5)nm,α=90.000(5)o,β=114.491(5)o,γ=90.000(5)o,V=2.858 (2)nm3,Z=4,R1=0.0424,w R2=0.1227。Under hydrothermal conditions, a new 2 D layer complex, [Co(L)2(H2O)2]·3 H2O(HL = 4-(3-(pyrazin-2-yl)-1 H-pyrazol-1-yl)benzoic acid), has been prepared by using 4-(3-(pyrazin-2-yl)-1 H-pyrazol-1-yl)benzoic?acid, CoCl2·6 H2O and NH4 VO3 as starting materials and by controlling pH and temperature. The structure was characterized by single crystal X-ray analysis, elemental analyses, thermogravimetric analyses and infrared spectra. The results show that it belongs to C2/c space group, monoclinic system,with a = 2.6164(5) nm, b = 0.8401(5) nm, c = 1.4286(5) nm, α = 90.000(5)o, β = 114.491(5)o, γ = 90.000(5)o, V = 2.858(2) nm3, Z= 4, R1= 0.0424, wR2= 0.1227.
