合成了Co(Ⅲ)的2,2’-联吡啶配合物,经元素分析、红外、差热-热重等表征确定了其组成为[Co(C10H8N2)2CO3]NO3·5H2O.通过X-射线单晶衍射仪测定了其结构,配合物晶体属单斜晶系,C2/c空间群,晶胞参数:a=10.9541(17),b=16.071(2),c=14.462(3),α=90.00,β=101.991(2),γ=90.00°,V=2490.4(7)3,Z=4,F(000)=1208,S=1.026.配合物由配位阳离子[Co(C10H8N2)2CO3]+、平衡阴离子NO3-,结晶水分子构成.在配位阳离子中,每个钴原子与来自两个2,2’-联吡啶的4个氮,碳酸根的两个氧配位,形成了畸变的八面体构型.CCDC:621673.图4,表2,参8.
The composition of [Co (C10H8N2) 2CO3] NO3 · 5H2O was confirmed by elemental analysis, IR, DTA-TG, The crystal structure of the complex is monoclinic and C2 / c space group. The unit cell parameters are a = 10.9541 (17), b = 16.071 (2), c = 14.462 (3) α = 90.00, β = 101.991 (2), γ = 90.00 °, V = 2490.4 (7) 3, Z = 4, F (000) = 1208, S = 1.026. The complex consisted of the coordination cation [Co (C10H8N2 ) 2CO3] +, an equilibrium anion NO3-, a crystal water molecule In the coordination cation, each cobalt atom is coordinated with two oxygen atoms from four nitrogen and carbonate groups of two 2,2’-bipyridines, Formed a distorted octahedral configuration.CCDC: 621673.
