The title compound, (C24H20P)2(C6H4N2O6S2)CuI·0.34H2O, was obtained by the slow evaporation of a solvent from an acetonitrile solution containing a mixture of (PPh4)2N,N′-disulfobenzoquinonediimine and CuI. The structure consists of a one-dimensional metal-organic framework of the dianion and CuI. The anionic chains are surrounded by relatively large counter-cations, and are thus well isolated from each other.
