Synthesis and Structure of Tetrahedral [Zn(maltol)2Cl2], Exhibiting Monodentate Coordination of Neutral Maltol
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).
期刊介绍：
Journal of Chemical Crystallography is an international and interdisciplinary publication dedicated to the rapid dissemination of research results in the general areas of crystallography and spectroscopy. Timely research reports detail topics in crystal chemistry and physics and their relation to problems of molecular structure; structural studies of solids, liquids, gases, and solutions involving spectroscopic, spectrometric, X-ray, and electron and neutron diffraction; and theoretical studies.
