Hi Amshumali, I suggest you to use LAN2DZ

Iman Rajaei

hello Amshumali,i reccommand you to use the GAUSSIAN software suite and DFT calculations with the B3LYP level of theory with the 6-31++G(d,p) basis

set for the main group elements and LanL2Dz for metals.

Bhawana Pandey

Lanl2dz is best as a basis set. One should also add ECP for the same.
