Polyatomic Molecules of Superheavy Elements

26VE SC RECPs and corresponding (6p6sdlf)/[5p5sdlf] valence basis sets were used for Xe, Rn and element (118), and a (9s5pld)/[4s2pld] all-electron 

The AREP-HF and REP-KRHF optimized bond lengths of RgF2 and RgF (Rg=Xe, Rn, and the element 118), which have and molecular symmetry, respectively. Units are in A. 

Optimized bond lengths of Rgp2 (Rg=Xe, Rn, and element 118) at the HF, MP2, CCSD and CCSD(T) levels of theory using AREPs. The molecular symmetry is Units are in A.
