以2,2′-联吡啶和硝酸根为混合配体,通过水热反应合成了一个新的钴(Ⅱ)配合物[Co(2,2′-bipy)2(NO3)]2SO4.(H2O)5,用元素分析、红外光谱、X-射线单晶衍射表征了配合物的结构。标题配合物晶体属单斜晶系,P2(1)/n空间群,晶体学参数:a=0.70932(9)nm,b=1.9528(2)nm,c=1.6841(2)nm,β=96.835(2)°,V=2.3161(5)nm3,Z=2,D=1.495g/cm3。配合物中每个钴(Ⅱ)离子与两个2,2′-联吡啶分子中的4个N原子、1个硝酸根的两个O原子形成六配位的变形八面体结构。
A new cobalt (Ⅱ) complex [Co (2,2’-bipy) 2 (NO3)] 2SO4 was synthesized by hydrothermal reaction using 2,2’-bipyridyl and nitrate as ligands. ) 5, The structure of the complex was characterized by elemental analysis, IR and X-ray single crystal diffraction. The title complex crystallizes in the monoclinic space group P2 (1) / n with crystallographic parameters of a = 0.70932 (9) nm and b = 1.9528 (2) nm with c = 1.6841 (2) °, V = 2.3161 (5) nm3, Z = 2, D = 1.495 g / cm3. Each cobalt (Ⅱ) ion in the complex forms a hexacoordinated deformed octahedral structure with two nitrogen atoms of two 2,2’-dipyridyl and two oxygen atoms of one nitrate.
