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. Graphical Abstract: A view of the tetrahedral [Zn(Hmalt)₂Cl₂] (Hmalt = neutral maltol, C₆H₆O₃).[Figure not available: see fulltext.]
