In this case, since I'm still getting the NaN, is it possible that something like this: &KIND Cu1 ELEMENT Cu BASIS_SET DZVP-MOLOPT-SR-GTH POTENTIAL GTH-PBE-q11 &BS &ALPHA NEL -1 0 L 0 2 N 4 3 &END &BETA NEL -1 -2 L 0 2 N 4 3 &END &END &END KIND &KIND Cu2 ELEMENT Cu BASIS_SET DZVP-MOLOPT-SR-GTH POTENTIAL GTH-PBE-q11 &BS &ALPHA NEL -1 -2 L 0 2 N 4 3 &END &BETA NEL -1 0 L 0 2 N 4 3 &END &END &END KIND Can give me the desired 5 electrons spin up and 4 spin down (and vice versa)? <div>----------</div>Henrique C.

Copper is [Ar] 3d10 4s1 and since I want to get Cu(II) my goal is [Ar] 3d9 (with one unpaired electron).
