Abstract

A mini review on the study concerning water stability of coordination polymers (CPs) is presented. Next, following the procedure proposed recently by Gelfand and Shimizu (Dalton Trans 45:3668-3678, 2016) the stability of three cysteine (Cys)containing CPs is investigated. The stability of studied CPs decreases in the order: Zn(Cys)(2)>Mg(Cys)(2)>Ca(Cys)(2) H2O. For the latternever reported before, the structure is additionally determined and it is proved that water is located in the first coordination sphere. It is shown that for nonporous CPs, in contrast to the porous ones, the immersion in water at 20 degrees C is more drastic for studied solids than the harsh humid conditions (80 degrees C at 90% R.H.). Finally all materials are assigned to the hydrolytic stability groups and it is concluded that the stability of studied CPs correlates well with the standard reduction potentials. This leads to the conclusion that the application of more inert metal as a node causes larger stability of studied CPs.
