Crystal structure of potassium [[2-[2-[2-[2-[2-[2-[2-(2-hydroxyethoxy)phenoxy]ethoxy]phenoxy]ethoxy]phenoxy]ethoxy]phenoxy]methyl]benzoate (2) has been determined. The backbone forms pseudocycle by head-to-tail hydrogen bonding. Conformations about C–C and C–O bonds are gauche and trans respectively, except for two of the C–O bonds which are gauche to make the pseudocyclic backbone bend like seam of a tennis ball. Ten oxygens except for one of the benzoate group coordinate with the potassium ion.
