Structural studies in the ruthenium(II)/(±)-ortho-Phenylenebis{methyl(phenyl)-phosphine/arsine} system. I. Crystal structure of trans-Carbonylhydridobis-[(±)-ortho-phenylenebis {methyl(phenyl)phosphine)]ruthenium(II)hexafluorophosphate(V)-acetone (1/2)

Abstract

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.
