Abstract Reactions of N,2-dihydroxy-3-methoxybenzamide (H3L) with transition metal acetates in the presence of pyridine and/or 2,2′-bipyridine under solvothermal conditions give two pentanuclear complexes, [Zn5L2(CH3COO−)4(py)3] (1) and [Co5L2(CH3COO−)4(py)(2,2′-bipy)2] (2). Photoluminescence studies indicate strong purple emission for 1 in the solid state at room temperature. Variable-temperature dc magnetic susceptibility studies of 2 reveal that antiferromagnetic CoII···CoII exchange interactions exist in 2. Graphical Abstract

两个五核团簇：合成、晶体结构、发光和磁性

摘要 N,2-二羟基-3-甲氧基苯甲酰胺 (H3L) 与过渡金属乙酸盐在吡啶和/或 2,2'-联吡啶存在下在溶剂热条件下反应得到两个五核配合物，[Zn5L2(CH3COO−)4(py )3] (1) 和 [Co5L2(CH3COO−)4(py)(2,2'-bipy)2] (2)。光致发光研究表明室温下固态的 1 发出强烈的紫色光。2的变温直流磁化率研究表明2中存在反铁磁CoII…CoII交换相互作用。
