Özet

The structure of Zn(HA)(2.4)H2O (HA = ascorbate) has been examined by a number of techniques (C-13 NMR, H-1 NMR, IR, EI/MS and TGA) and also modeled by the semi-empirical PM3 method. The experimental and computational results agreed on a five-fold coordination around Zn(II) where one ascorbate binds monodentately, the other bidentately and two water molecules occupy the remaining sites of a distorted square pyramid.
