Crystals of [H 5 O 2 ][Ru(CO) 3 Cl 3 ] · SbCl 3 are triclinic, space group P 1 , with unit cell of dimensions: a = 7.129(2), b = 10.129(3), c = 10.997(3) Å, α = 75.40(2)°, β = 97.17(2)°; γ = 120.94(2)°. The structure was solved from X‐ray diffractometer data by Patterson and Fourier synthesis and refined by full matrix least‐squares method to R = 3.02% for 3268 independent reflections. The [Ru(CO) 3 Cl 3 ] − anion has an approximately octahedral fac configuration. The antimony atom has three chlorine neighbours at 2.387(2), 2.364(2) and 2.368(2) Å giving the expected angular conformation and three other neighbours at longer distances completing with the lone pair a monocaped octahedral environment around antimony. The acidic hydrogen has been transfered to two water molecules giving an asymmetric [H 5 O 2 ] + ion with a very short hydrogen bond of 2.373(9) Å.
