Abstract Eleven mixed-ligand chelates of Ni (II) containing a molecule of N,N-di-, N,N,N′-tri-, or N,N,N′,N′-tetramethylethylenediamine, and a tropolonate (trop) or hinokitiolate (hino) ligand, were prepared, and their electronic spectra in solid state and in various organic solvents were studied. Most systems studied were green, containing octahedral chelate species [Ni (trop\hino) (diamine) (H2O\Solvent)
摘要包含11个分子的N,N-di-,N,N,N'-tri-或N,N,N',N'-四甲基乙二胺的Ni(II)混合配体螯合物和对苯二酸酯(trop )或扁桃酸酯(hino)配体的制备,并研究了它们在固态和在各种有机溶剂中的电子光谱。研究的大多数系统是绿色的,包含八面体螯合物种[Ni(trop \ hino)(二胺)(H2O \ Solvent)2] +或[Ni(NO3)(trop \ hino)(二胺)],但是有些是红色的,包含正方形平面[Ni(trop \ hino)(diamine)] +,有时在溶液中观察到八面体和正方形平面物种之间的平衡。可以指出与相应的Ni(II)的二胺-β-二酮酸酯螯合物具有很强的光谱相似性。
