The structure of the title compound, (C36H30NP2)2[OsCl5F].H2O, has been determined by single-crystal X-ray diffraction at 208 K. The octahedral [OsCl5F]2− complex anions are completely ordered in an A2B-type lattice. The monoclinic unit cell contains four formula units, each with a solvent water molecule linked to the F ligand by a hydrogen bond [OF 2.737 (8) Å]. The Os—F bond [1.960 (4) Å] is weakened by a trans influence and, correspondingly, the Os—Cl1 bond [2.307 (2) Å] trans to Os—F is strengthened compared with the average Os—Cl bond length along the Cl—Os—Cl axes of 2.339 Å.
