Structural studies on polynuclear osmium carbonyl hydrides. 14. X-ray diffraction study of (.mu.-H)4Os4(CO)11(CNMe), including the direct location of all four bridging hydride ligands

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) �, β 90.97(7)�, 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)�.

Inherent Tendency

Structural studies on model compounds Boc–NH–(CH2)2–NH–Boc (1) and Boc–NH–(CH2)3–NH–Boc (2) have shown the inherent tendency of the propylene group to adopt a folded conformation, which may help in peptide and peptide nucleic acid (PNA) design.

The crystal and molecular structure of the title complex, cis-[Ru(CO)Cl2(dmso)(opmpp)] (1) (dmso ≡ dimethyl sulfoxide, Me2SO; opmpp ≡ (�)-ortho-phenylenebis {methyl(phenyl)phosphine},[o-C6H4(PMePh)2]), has been determined by a single-crystal X-ray diffraction study at 295(1) K, being refined to a residual of 0.050 for 6115 independent 'observed' reflections. Crystals are monoclinic, P21/c, a 11.180(7), b 12.957(6), c 17.567(9) �, β 90.88(5)�, Z 4. The ruthenium-chlorine distances, trans to phosphine and carbonyl ligands, respectively, are 2.469(2), 2.446(2) �; the ruthenium-phosphine distances, trans to the chloride and dimethyl sulfoxide ligands, respectively, are 2.292(1), 2.313(2) �. Ruthenium-sulfur (dmso) is 2.380(2) �, while the ruthenium-carbon(CO) is c. 1.72 �. For cis-[Ru(CO)2Cl2(opmpa)] (2) (opmpa ≡ (�)-ortho-phenylenebis{methyl(phenyl)- arsine}, [o-C6H4(AsMePh)2]), refinement led to a residual of 0.036 for 2423 independent 'observed' reflections. Crystals are monoclinic, P21/c, a 10.497(3), b 11.586(7), c 20.341(9) �, β 105.31(4)�, Z 4. Ruthenium-arsine distances, trans to carbonyl and chlorine ligands, respectively, are 2.404(1), 2.455(1) �. Ruthenium-chlorine distances, trans to arsine and carbonyl ligands, respectively, are 2.443(3), 2.433(2) �, while ruthenium-carbon(CO) distances, trans to arsine and chlorine ligands, respectively, are 1 .920(8), 1 .872(8) �.
