Dioxouranium(VI) carboxylate polymers: synthesis and characterization of tractable coordination polymers and evidence for rigid rod conformation

“…25 The evaluation of coordination polymers with SEC has seldom been accomplished.40,41 Inorganic materials tend to suffer from secondary phenomena which exaggerate molecular size. 42 The SEC evaluation of bis(acetato)dioxouranium(VI) in a NMP medium reproducibly gives a sharp, symmetrical peak at an elution volume consistent with a monomeric species30 (see Figure 4). This behavior suggests that large secondary effects are not inherent to the SEC of dioxo- uranium(VI) species.42 However, secondary effects have been observed in several of the species reported here.…”
