Abstract

The structure of the title compound, [Ag(C18H15P)(4)](2)[Ag(C6H6NO6)(C18H15P)], exhibits trigonal (P (3) over bar) symmetry, with a C-3 axis through all three complex ions, resulting in an asymmetric unit that contains one third of the atoms present in the formula unit. The formula unit thus contains two of the cations, one anion and disordered molecules of methanol as the packing solvent. Attempts to refine the solvent model were unsuccessful, indicating uninterpretable disorder. Thus, the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18] was applied, accounting for 670 electrons per unit cell, representing approximately 18 molecules of methanol in the formula unit. The stated crystal data for M-r, mu etc do not take these into account.
