Abstract

Recrystallization of [Zn(malt)₂(H₂O)_1.5] (malt = maltolato(-1), C₆H₅O₃) from a concentrated aqueous solution acidified with HCl to pH 3.0 yielded colorless crystals of [Zn(Hmalt)₂Cl₂] (Hmalt = neutral maltol, C₆H₆O₃). The Zn(II) site exhibits distorted tetrahedral coordination through bonding to two chloride ligands and to two neutral maltol ligands, each bonding through the ketonic oxygen. [Zn(Hmalt)₂Cl₂] is a unique example of a neutral monodentate coordination by the maltol ligand.

中性麦芽糖醇单齿配位的四面体[Zn(麦芽糖醇)2Cl2]的合成与结构

[Zn(malt)2(H2O)1.5] (malt =麦芽糖(-1)，C6H5O3)从HCl酸化至pH 3.0的浓水溶液中再结晶得到[Zn(Hmalt)2Cl2] (Hmalt =中性麦芽糖，C6H6O3)的无色结晶。Zn(II)位点通过与两个氯离子配体和两个中性麦芽糖醇配体的键合表现出扭曲的四面体配位，每个配位都通过酮氧键合。[Zn(Hmalt)2Cl2]是麦芽糖醇配体中性单齿配位的独特例子。[Zn(Hmalt)2Cl2] (Hmalt =中性麦芽糖醇，C6H6O3)的四面体图。
