摘要
以N,N′-乙二水杨酰胺合镍酸钠同二价金属离子和2,2-联吡啶(bpy)或1,10菲绕啉(phen)反应制得双核配合物,[Ni(samen)Cu(L)]和[Ni(samen)Ni(L)_2](L=bpy,phen).经元素分析。红外、电子光谱等方法已推定[Ni(samen)]~2-中的Ni(Ⅱ)的配位环境为平面四方型,而被bpy或phen配位的Cu(Ⅱ)和Ni(Ⅱ),分别为平面四方型和畸变八面体构型。 据此,本文指派了配合物的电子光谱,评价了Dq,B,β等配位场参数,并且用配位场理论模型算出了有效磁矩,Ni(Ⅱ)-Cu(Ⅱ)配合物的g_(11),与g_1,结果理论值与实验值相当吻合。
The complexes, [Ni(samen)Cu(L)] and [Ni(samen)Ni(L)2](L = bpy, phen) have been synthesized by the reaction of sodium N,N'-ethylenedisalicylamidoniccolate(Ⅱ) Na2[Ni(samen)], a divalent metal ion and 2,2'-dipyridyl or 1,10-phenanthroline. Based on IR, elemental analyses and electronic spectra, it is proposed that the nickel of [Ni(samen)]2- have square planar environment, and the copper or the nickel coordinated by L has square planar or distorted octahedron structure. The absorption bands of d-d transitions were assigned, and the values of Dq ,B,β were evaluated. The effective magnetic moment of these complexes and g11,g1 of [Ni(samen)Cu(L)] were derived from the parameters with aid of ligand field method. Fairly good agreement has been obtained between the calculated and experimental values.
