【 摘 要 】

The title pseudo-polymorph of 3-(tri­phenyl­phospho­ranyl­idene)-2,5-di­hydro­furan-2,5-dione crystallizes with a tetra­hydro­furan solvent mol­ecule, viz. C22H17O3P·C4H8O. The succinic anhydride ring is approximately planar (r.m.s. deviation = 0.032 Å). The tetra­hydro­furan mol­ecule is disordered over two orientations about a pseudo-twofold axis with refined occupancy ratio 0.718 (4):0.282 (4). In the crystal, C—H⋯O hydrogen bonds link mol­ecules of the di­hydro­furan-2,5-dione derivative into chains parallel to the b axis and arranged into layers stacked along [100] alternating with hydrogen-bonded tetra­hydro­furan layers.
