Synthesis and crystal structure characterization of zinc (II) tetronic acid complexes

Abstract

The synthesis and characterization of two new tetronic acid zinc (II) complexes of the empirical formulae [Zn (L-H)2(H2O) 2] (1) and [Zn (L-H)2(H2O)(MeOH)]H2O (2) found within the same crystal are reported. The zinc ions bind through alkoxide and carbonyl groups of the ligand 3-methoxycarbonyl-5-phenyl tetronic acid (LH) as indicated by 1H NMR and X-ray crystallographic studies. These complexes promote intra- and intermolecular interactions, such as hydrogen bonding and stacking, giving place to the formation of molecular aggregates. Copyright © 2010 K. C. Prousis et al.
