    Notizen: Summary The displacement of bicarbonate anion in the (NH3)3ZnII(HCO 3 − ) complex with water has been studied throughab initio calculations. It has been found that H2O binds to the (NH3)3ZnII(HCO 3 − ) species yielding a stable pentacoordinate (NH3)3ZnII(HCO 3 − )(H2O) complex. The results also indicate that deprotonation of water in the pentacoordinate species facilitates the release of HCO 3 − , although, the presence of HCO 3 − in the coordination sphere of ZnII makes such deprotonation more difficult. Environmental effects have been considered in the study of HCO 3 − /H2O exchange.

    Notizen: Summary.  The displacement of bicarbonate anion in the (NH3)3ZnII(HCO- 3) complex with water has been studied through ab initio calculations. It has been found that H2O binds to the (NH3)3ZnII(HCO- 3) species yielding a stable pentacoordinate (NH3)3ZnII(HCO- 3)(H2O) complex. The results also indicate that deprotonation of water in the pentacoordinate species facilitates the release of HCO- 3, although, the presence of HCO- 3 in the coordination sphere of ZnII makes such deprotonation more difficult. Environmental effects have been considered in the study of HCO- 3/H2O exchange.
