Quantum chemical study of PtFn and PtCln (n = 1-6) complexes: An investigation of superhalogen properties

► Present study points that, PtFn and PtCln belong to the class of superhalogens. ► Here using DFT, we show that Pt can have oxidation states ranging from +1 to +6. ► Large HOMO-LUMO gap reveals stability of subject compounds. ► The binding energy of NaPtF4 and NaPtCl4 are larger than that of NaF and NaCl.
