苦味酸盐与4′-硝基苯并-15-冠-5配合物的合成与表征

Synthese and Characterization of Picrates and Nitro-4′-Benzo-15-Crown-5 Complexes

在乙腈 乙醇 水(2+2+1,V+V+V)的混合溶剂中制备了六种金属(锰、钴、镍、铜、锌、镉)苦味酸盐与4′ 硝基苯并 15 冠 5的固态配合物,其组成为M(pic)2·2L·xH2O(M=Mn,Cu,x=2,M=Co,Ni,Zn,Cd;x=4;pic=苦味酸根;L=4′ NO2B15C5),并通过元素分析、红外光谱、紫外光谱和摩尔电导等对该系列配合物进行了表征,证明该系列配合物的摩尔组成比为2∶1,给以苦味酸盐为对阴离子的过渡金属冠醚配合物领域增添了新内容。

Six kinds of metal picrates and Nitro-4′-Benzo-15-Crown-5(L) complexes,having the stoichiometric formula of M(pic)_2·2L·xH_2O (M=Mn,Cu,x=2;M=Co,Ni,Zn,Cd,x=4;pic=picrate anion,L=4′-NO_2B15C5),were prepared in a 2+2+1 (V+V+V) mixed solvent of MeCN,EtOH and H_2O,and Characterized by EA,IR,UV and molar conductance. It was proved that molar rate of these set of complexes is 2∶1,so,new content is added to the field of transition metal crown complexes with picrates as couple anion.
