Yes, indeed, you could try to use R.E.D. Server. However, two comments:
- The best bet might be to use R.E.D. Server in its "Mode 2";
i.e. see: http://q4md-forcefieldtools.org/REDS/popup/popmodes.php
This means you get the optimized geometry for your complex without
R.E.D. Server
& you load the corresponding QM output as input in R.E.D. server with
the P2N input file.
Moreover, here, you might consider a specific QM program for this
geometry optimization step.
See
http://q4md-forcefieldtools.org/REDS/faq.php#12
- That being said, we are going to release a specific approach for
RESP charge derivation of metal complexes. However, this is not yet
available:
See: http://q4md-forcefieldtools.org/REDS/popup/news.php
