STABILITY OF THE SILICON RUTHENIUM BOND IN THE PRESENCE OF A STRONG NUCLEOPHILE - PHASE-SENSITIVE H-1-NMR COSY AND CRYSTAL-STRUCTURE OF RU(CO)2(NH2CH2C6H5)2(SI(C6H5)(CH3)2)I

The ruthenium(II) complex RU(CO)2(NH2(NH2CH2C6H5)2(Si(C6H5)(CH3)2)I ha s been prepared by the reaction of RU(CO)4(Si(C6H5)(CH3)2)I with benzy lamine. Two-dimensional homonuclear H-1 NMR experiments examine the sc alar coupling of the enantiotopic amino and methylene protons of the b enzylamine ligand. X-ray analysis of Ru(CO)2(NH2CH2-C6H5)2(Si(C6H5)(CH 3)2)I.1/3C5H12 (triclinic; P1BAR; a=14.266(4), b=15.748(5), c=20.082(6 ) angstrom; alpha=94.38(3), beta=96.30(2), gamma=101.52(2)-degrees) in dicates three crystallographically unique complexes form a clathrate w ith a pentane guest.
