Comparative analysis of the structural features of the recovered polymeric phases of CO2 (pa,rc[CO2] at 200 K) and CO+O2 (pa,rc[CO+O2] at 300 K). a Pairwise radial distribution function, g(r), for both systems at near-ambient pressures. b Comparison of chain structures, with carbon and oxygen atoms shown in gray and red, respectively. Here, 5l, 5n, and 6i indicate 5-member chain-linked, 5-member networked, and 6-member interlocked rings, respectively. c Partial crystal orbital Hamiltonian population (pCOHP) for pa[CO+O2] for C-centered (top-left) and O-centered (top-right) bondings, as well as the integrated COHP as a function of bond order for selected pressures. d Nearest neighbor coordination number (NNCN) histograms for C−O, O−C, O−O, and C−C pairs.
