Dear Fabian,

Yes, we have done it recently ( Initially, we prepared
the parameters for acetonitrile using antechamber of a QM optimized
geometry. I compared it with previously published parameters and it was
almost the same (charge, bond length, force constants etc). Thereafter1 we
used Packmol to produce a solvent box. However, our intention was to study
the effect of applied electric field on this system which worked well.

However, if you are not fond of packmol, there is an alternative way using
#load mol2 of acetonitile (ACN) generated from antechamber and then use it
as solvent box instead of TIP3PBOX or SPCBOX, eg.,
ACE=loadmol2 ACE.mol2
solventBox mol ACE 10.0
