At high pressures of CO, the Ag+ salt of the weekly coordinating anion [Nb(OTeF5)6]- takes up three equiv. CO reversibly both in the solid state and in 1,1,2-C2Cl 3F3 solution; the CO ligands can be removed from [Ag(CO)3][Nb(OTeF5)6] under vacuum at 25 °C but none are removed at -78 °C; IR ν(CO) values are 2192 cm-1 for [Ag(CO)3]+, 2198 cm-1 for [Ag(CO) 2]+, and 2208 cm-1 for [AgCO]+.
