Tris[3‐(3‐dimethylamino‐1‐oxoprop‐2‐enyl)phenyl]phosphaneoxide, which can be synthesized quantitatively by oxidation of the corresponding phosphane, crystallizes in the trigonal space group R $\bar {3}$ . Because of the four different strong proton accepting sites (1 × P=O, 3 × C=O), this molecule can form P=O ··· H–O–H ··· O=P and C=O ··· H–C hydrogen bonds in the solid state, which results in the generation of two interpenetrating networks. In the cavities of the solid‐state structure, water and acetone are enclosed.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
