基于水杨酰基缩对硝基水杨酰肼及吗啡啉的三核镍(Ⅱ)配合物的合成、晶体结构与磁性质

合成了1个含水杨酰基缩对硝基水杨酰肼（H₃-o-nbzshz）和单啮N-杂环分子吗啡啉（Mf）的镍（Ⅱ）配合物[Ni₃（o-nbzshz）₂（DMF）₂（Mf）₂]·2H₂O,并通过元素分析、红外、热分析以及单晶衍射等手段进行表征。标题配合物是由肼基N-N单键桥联3个金属中心形成的具有晶体学中心对称性的三核镍配合物结构,Ni1…Ni2原子间距为0.4586（1）nm。在配合物中,对称的Ni1原子与中间的Ni₂原子分别形成平面四方形和轴向伸长的八面体的配位构型。配合物通过分子间氢键作用构筑成二维超分子网络结构。并通过变温磁化率研究了化合物的磁性质。     

α、β、γ、δ-四(4-二甲氨基苯基)卟啉与钯(Ⅱ)显色反应的分光光度法研究

近年来国内外对卟啉衍生物在分析中的应用进行了广泛的研究,特别是非水溶性卟啉衍生物由于它们具有易合成,易提纯,结构类型多等特点而愈来愈得到重视。本文对非水溶性α、β、γ、δ-四(4-二甲氨基苯基)卟啉〔简称T(4-DMAP)P〕作显色剂测钯(Ⅱ)的反应进行了较系统的研究,找到了显色反应的最佳条件。测得表观摩尔吸光系数达5.7×10~6,是目前测痕量钯(Ⅱ)最灵敏的分光光度法。     

Synthesis,Structure and Luminescent Property of a New Zn(Ⅱ) Coordination Polymer Based on 1,3,5-Benzenetricarboxylate and 4,4'-Bipyridine Ligands

A new Zn(II) coordination polymer [Zn3(BTC)2(4,4'-bpy)(CO)2]n(1, H3 BTC =1,3,5-benzenetricarboxylic acid, 4,4'-bpy = 4,4'-bipyridine) has been prepared through urothermal reaction of zinc nitrate hexahydrate with 1,3,5-benzenetricarboxylic acid and 4,4'-bipyridine, and characterized by elemental analysis, IR spectroscopy, TGA and powder XRD, and its crystal structure was determined by single-crystal X-ray diffraction analysis. The title compound crystallizes in the monoclinic system, space group C2/c, with a = 10.262(3), b = 18.838(5), c =15.083(4) A, β = 99.203(4)o, V = 2878.3(14) A3, C30H14Zn3N2O14, Mr = 822.54, Z = 4, Dc = 1.898g/cm3, μ = 2.561 mm-1, F(000) = 1640, R = 0.0363 and w R = 0.0932 for 2828 observed reflections(I 2σ(I)). X-ray analysis shows that the asymmetric unit of the title compound contains two crystallographically unique Zn(II) atoms which are connected by BTC3- ligands and 4,4'-bpy coligands to form a 3D framework with 1D channels. The solid luminescence of ligand and the title complex was also studied at room temperature.
