Crystal structure of trans-Carbonylhydridobis-[(±)-ortho-phenylenebis {methyl(phenyl)phosphine)]ruthenium(II)hexafluorophosphate(V)-acetone (1/2) JF - Australian Journal of Chemistry JO - Aust. J. Chem. Y1 - 1983 VL - 36 IS - 2 SP - 259 EP - 265 KW - UR - https://doi.org/10.1071/CH9830259 N2 - The crystal and molecular structure of the title complex, trans-[RuH(CO)(opmpp)2]+ (PF6)-.2(CH3)2- CO [opmpp ≡ (±)-ortho-phenylenebis {methyl(phenyl)phosphine) , o-C6H4(PMePh)2], has been established by a single-crystal X-ray diffraction study at 295(1) K, being refined to a residual of 0.066 for 2293 independent 'observed' reflections. Crystals are monoclinic, C2/c, a 11.943(4), b 26.151(9), c 15.974(6) Å, β 90.97(7)º, Z 4. In the model adopted, the ruthenium atom is located on a crystallographic twofold axis; the carbonyl and hydrido ligands lie trans to each other and are disordered about the ruthenium atom. The ruthenium-phosphorus distances are 2.320(2) and 2.317(2)Å. ER -
