Ab-initio quantum-mechanical calculations are performed to determine structures and energetic of anions formed by the trimer of an acetonitrile molecule and two water molecules. In total, eight anion configurations corresponding to separate local minima of the anion potential energy surface are identified. All eight anions have positive vertical electron detachment energies. The identified anions belong to the following three categories: dipole-bound anions, anions where the excess electron is suspended between two fragments of the trimer, and solvated covalent anions.
