摘要 在2-醛基-8-羟基喹啉、组胺盐酸盐和醋酸镱体系下,制备了一个镱的配合物Yb_3(nma)_2(OAc)_7·2H_2O(1),[Hnma=N-(2-(8-hydroxylquinolinyl)methane(2-(4-imidazolyl)ethanamine)]。该结构具有一个醋酸桥连的特色的Yb_3结构基团。在配合物1的结构中存在3种不同的醋酸根离子的配位模式,分别是螯合、螯合桥连和桥连模式。配合物1在固体和甲醇溶液中均可显示镱离子的特征近红外光。 Self-assembly of 2-aldehyde-8-hydroxyquinoline, histamine dichloride and Yb(OAc) 3 · 6H20 affords a lanthanide complex Yb3 (nma) 2 (OAc)7· 2H20 ( 1 ), imidazolyl) ethanamine) J. The structure of complex 1 [ Hnma = N- ( 2- ( 8-hydroxylquinolinyl ) methane ( 2- ( 4- is featured by the trinuclear Yb3 moiety, bridging by the acetate groups. The diverse coordination modes for the acetate are found as chelating, chelating bridging and bridging modes, respectively. It is noted that complex 1 exhibits essential NIR luminescence of Yb3+ ion in solid and in CH3OH solution.
