%X The crystal structure of the title compound, [Os(phen)3](ClO4)2.c. 1H2O, has been determined by single-crystal X-ray diffraction methods at 295 K, being refined to a residual of 0.043 for 3477 'observed' independent reflections. Crystals are monoclinic, C2/c, a 35.94(2), b 16.020(5), c 12.370(5) Å, &#946; 102.38(3)º, Z 8, and are isostructural with the copper(II) analogue. Osmium-nitrogen distances range from 2.066(7) to 2,082(7) Å (mean, 2.075 Å). Departures of the stereochemistry of tris- (&#945;, &#945;'-diimine)metal systems from the expectations of electron-pair repulsion theory are examined.
