with Cu(II)(N–N) complex to synthesize multinuclear [Ni(dioxime)2Cu2(N–N)2](ClO4)2 oxime complexes (3–7) where N–N = 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen), 3,3′-dicarboxy-2,2′-bipyridine (dcbpy), 4,5-diazafluoren-9-one (dafo) and 1,10-phenanthroline-5,6-dione (dione). The mononuclear complex [Ni(dioxime)2] (2) was used as a precursor for building multinuclear oxime complexes (3–7). In this
合成了不对称的二肟肟配体及其单核和多核金属配合物,并通过1 H和13 C NMR光谱,FT-IR,UV-Vis,元素分析,熔点测量,LC-MS光谱,摩尔电导率测量和磁化率进行了表征。和循环伏安技术。我们首先制备了新的不对称二肟配体(1)及其单核[Ni(二肟)2 ]络合物(2)。然后,用Cu(II)(N–N)配合物取代分子内的OH桥,以合成多核[Ni(二肟)2 Cu 2(N–N)2 ](ClO 4)2肟配合物(3– 7),其中N–N = 2,2'-联吡啶(bpy),1,10-菲咯啉(phen),3,3'-二羧基-2,2'-联吡啶(dcbpy),4,5-二氮杂芴- 9-一(dafo)和1,10-菲咯啉-5,6-dione(dione)。该单核配合物[镍(二肟)2 ](2)作为前体用于构建多核络合物肟(3 - 7)。在本文中,我们的目标是研究这种新配体及其金属配合物的光谱,电化学和催化性能。
