solvatomers 

https://doi.org/10.1351/goldbook.08209
Isomers that differ in their solvation environment.
Notes:
  1. Because the solvation environment fluctuates rapidly, solvatomers interconvert rapidly.
  2. Species that differ in the type of solvent molecules should not be called solvatomers because they are not isomers.
