第一个混合价一维链配位聚合物的合成、结构和性质(英文)

Synthesis, structure and characterization of the first mixed-valence Co~Ⅱ, Co~Ⅲ one-dimensional chain coordination polymer

合成和表征了混合价一维链配位聚合物 [CoⅡ2 CoⅢ(nta) 2 (azpy) 4 (H2 O) 6]·[CoⅡCoⅢ(nta) 2(azpy) 2 (H2 O) 2 ]·4H2 O(nta为氮三乙酸 ,azpy为 4 ,4′ 偶氮联吡啶 )。晶体结构分析表明 ,它由带“侧臂”的一维链阴离子 [CoⅡCoⅢ(nta) 2 (azpy) 2 (H2 O) 2 ]- 和三核阳离子 [CoⅡ2 CoⅢ(nta) 2 (azpy) 4 (H2 O) 6]+组成。通过4 ,4′ 偶氮联吡啶的吡啶环的π π堆积作用 。

The mixed valence complex [Co Ⅱ 2Co Ⅲ(nta) 2(azpy) 4(H 2O) 6]·[Co ⅡCo Ⅲ(nta) 2(azpy) 2(H 2O) 2]·4H 2O was synthesized and characterized. X ray single crystal structure analysis showed that it is composed of one dimensional chain anion [Co ⅡCo Ⅲ(nta) 2(azpy) 2(H 2O) 2] - with “open sidearms” and “H like” trinuclear cation [Co Ⅱ 2Co Ⅲ(nta) 2(azpy) 4(H 2O) 6] +. The stack of one dimensional chain anions forms two dimensional rhombus pores through π π stacking of pyridyl rings from azpy.
