Recrystallization of [Zn(malt).sub.2(H.sub.2O).sub.1.5] (malt = maltolato(-1), C.sub.6H.sub.5O.sub.3) from a concentrated aqueous solution acidified with HCl to pH 3.0 yielded colorless crystals of [Zn(Hmalt).sub.2Cl.sub.2] (Hmalt = neutral maltol, C.sub.6H.sub.6O.sub.3). 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).sub.2Cl.sub.2] is a unique example of a neutral monodentate coordination by the maltol ligand. Graphical Abstract A view of the tetrahedral [Zn(Hmalt).sub.2Cl.sub.2] (Hmalt = neutral maltol, C.sub.6H.sub.6O.sub.3).
