The title compound, C25H22P+·C5H5O2-, crystallizes in space group P21/c. The phosphonium cations form zigzag chains with P…P distances of 6.475 (1) and 8.287 (2) Å, and are related by inversion centres. Two types of attractive edge-to-face phenyl interactions exist, resulting in a dominant supramolecular motif. The glutaconaldehyde anions occupy the interchain spacing and hold adjacent chains together via multiple C-H…O hydrogen bonds. The bond-length alternation, a parameter which reveals the non-linear optical efficiency at the molecular level, is optimized in the chromophore anion.
