【摘要】 |
|
Three new cobalt complexes were synthesized by solid-state reaction at room temperature and the resultant Co complexes reacted with two equivalent oxygen molecules at room temperature to produce the oxygenated complexes [Co · (L1)2 · (O2)2](NO3)2 · 2H2O (L1 = N, N′-bis(4-hydroxyl-3-methoxy-benzyl)-diethylenetriamine), [Co · (L2)2 · (O2)2] (NO3)2 · 2H2O (L2 = N, N′-bis(4-hydroxyl-3-methoxybenzyl)-triethylenetetramine), and [Co · (L3)2 · (O2)2](NO3)2 · 2H2O (L3 = N, N′-bis(4-hydroxyl-3-methoxy-benzyltetraethylenepentamine). The oxygenated complexes were characterized by elemental analysis, IR (Infrared), 1H-NMR (Nuclear Magnetic Resonance), and UV-Vis (Ultraviolet Visual) spectrometry, and TG/DTA (Thermogravimetry/Differential Thermal Analysis) analysis, and molar conductance. The coordinated oxygen contents in the oxygenated com plexes were also determined by weight method. It was supposed that only one O2 molecule coordinated to the Co ion forming a superoxo type oxygenated complex. |
