摘要
选择多齿阴离子HXTRA^(4-)为配体,通过分子自组装方法,得到两个钴配合物,[Na(H_2O)_3Co(HXTRA)]_n(1)和{[Na_2(H_2O)_2Co_2(HXTRA)_2]·3.5H_2O}_n(2),并对其进行了元素分析、红外光谱、紫外光谱及X-射线单晶结构表征.结果表明,钠离子在两个配合物的形成过程中起到了关键作用.
Using polydentate HXTRA^(4-) as the ligand,two new complexes,[Na(H_2O)_3Co (HXTRA)]_n(1) and {[Na_2CH_2O)_2Co_2(HXTRA)_2]·3.5H_2O}_n(2),were synthesized and characterized by elemental analysis,IR spectroscopy,UV-vis spectroscopy and X-ray crystal structure analysis.Sodium ions templating effect is found to play a significant role in the assembly of the two complexes.
