合成了3个四苯基[b,f,j,n][1,5,9,13]四氮杂环十六碳炔镍轴向氮碱加合物[Ni(TAAB)(L)_2](BF_4)_2(L为吡啶、咪唑、DMF)以及4,4′-联吡啶桥联配合物[Ni(TAAB)(μ-4,4′-bipy)]。[(ClO_4)_2·H_2O]_((??))。用元素分析、IR和热分析对标题化合物作了表征。双吡啶加合物的晶体结构显示,TAAB大环呈马鞍形结构,轴向配位的吡啶环平面相互垂直,轴向的2个Ni—N键长明显比赤道平面的4个Ni—N键长大,形成拉长的配位八面体。4,4′-联吡啶配合物的变温磁化率表明,镍(Ⅱ)离子间存在反铁磁性磁交换相互作用。
Three tetraphenyl [b, f, j, n] [1,5,9,13] tetraazacyclohexadecanedithine nickel base azide adduct [Ni (TAAB) ] (BF_4) _2 (L is pyridine, imidazole, DMF) and 4,4’-bipyridyl bridged complex [Ni (TAAB) [(ClO_4) _2 · H_2O] _ (()). The title compound was characterized by elemental analysis, IR and thermal analysis. The crystal structure of the bipyridine adduct shows that the TAAB macrocycle has a saddle-shaped structure. The axial plane of the pyridine ring is perpendicular to each other. The two Ni-N bonds in the axial direction are significantly longer than the four Ni-N bonds in the equatorial plane Grow up, forming elongated coordination octahedron. The temperature-dependent magnetic susceptibility of the 4,4’-bipyridine complex indicates that there is an antiferromagnetic magnetic exchange interaction between the nickel (II) ions.
