Current work deals with the structural and electronic properties of the cis-platin by employing the B3LYP density functional theory with SDD basis sets at the Gaussian 09 package of programs. We showed a good relax was obtained for the cis-platin. The great contribution for constructing the molecular orbitals is due to the outer electrons in the platinum metal with few contributions from the p-orbitals of the ligands, cis-platin has insulating behavior. Also, the cis-platin has low electronic softness and it needs high excitation energy to electron transfer or to accepting an electron from the surrounding species.
