摘要
A discrete cyclic water heptamer trapped inside a three-dimensional coordination polymer undergoes single-crystal to singlecrystal transformation to a new type of water heptamer containing a pentamer ring buttressed by a dimer, accompanied by phase transition below 273 K. The structural differences between the heptamers in BF4- and ClO4- salts have been attributed to the influence of the anions in the channels.
