Synthesis and spectroscopic characterization of copper, nickel and cobalt complexes with N-(N″,N″-disubstituted-aminothiocarbonyl)-N′-substituted benzamidines
A series of copper(II), nickel(II) and cobalt(III) complexes with N-(N″,N″-disubstituted-aminothiocarbonyl)-N′-substitutedbenzamides have been synthesized and characterized. 1H and 13C NMR spectra have shown a mer configuration for the CoL3 compounds. The NiL2 complexes have a square-planar structure. Electron spin resonance spectra have shown that the presence of a bulky substituent on the nitrogen
合成并表征了一系列具有N-(N '',N ''-二取代-氨基硫代羰基)-N'-取代的苯甲酰胺的铜(II),镍(II)和钴(III)配合物。1 H和13 C NMR光谱显示了COL 3化合物的mer构型。NiL 2复合物具有正方形平面结构。电子自旋共振谱表明,在氮供体原子上存在庞大的取代基会在CuL 2化合物的铜周围产生较大的四面体形变。循环伏安法已揭示了不可逆的氧化还原波,分别对应于Cu(III)Cu(II)和Cu(II)Cu(II)对。
