本文用2-咪唑乙酸(Hiaa),2,2'-联吡啶,氢氧化钠和六水合高氯酸锰在水和乙醇中反应合成了1个二维配位化合物{[Mn(iaa)(2,2'-bipyridine)(H2O)](CIO4)}n(1).单晶结构表明化合物1是1个新颖的二维双核锰配位聚合物.锰离子的配位构型为扭曲的八面体.每一个锰离子与3个配体配位,而每个配体与3个锰离子桥连.磁性研究表明1中Mn(Ⅱ)离子间存在弱的反铁磁偶合作用.%Slow evaporation of the reaction mixture of ligand 2-(1H-imidazol-1-yl)acetic acid (Hiaa), 2,2'-bipyridine, NaOH, and Mn(ClO4)2·6H2O in water/ethanol affords a complex {[Mn(iaa)(2,2'-bipyridine)(H2O)](ClO4)}n (1). Single crystal structure determination reveals that 1 is a novel two-dimensional dinuclear manganese coordination polymer.The local coordination environment around manganese ions is a distorted octahedron. Every manganese ion coordinates with three ligands, while each ligand acts as a bridge linking three Mn ions. Magnetic studies suggest a weak antiferromagnetic coupling interaction between two Mn(Ⅱ) ions.
