title: X-ray structure of [Ru3 O2 (NH3)14]6+, cation of the cytological reagent Ruthenium Red.
abstract: The X-ray crystal structure of [Ru3 O2 (NH3)14] (S2 O3)3 . 4H2 O, the thiosulphate salt of Ruthenium Red, has been determined. The cation contains an essentially linear N-Ru-O-Ru-O-Ru-N backbone formed from three ruthenium coordination octahedra, giving an effectively cylindrical shape to the ion. Resonance Raman spectra are consistent with retention of this structure in solution.
