| Abstract: | The ruthenium(II) complex Ru(CO)2(NH2(NH2CH2C6H5)2(Si(C6H5)(CH3)2)I has been prepared by the reaction of Ru(CO)4(Si(C6H5)(CH3)2)I with benzylamine. Two-dimensional homonuclear 1H NMR experiments examine the scalar coupling of the enantiotopic amino and methylene protons of the benzylamine ligand. X-ray analysis of Ru(CO)2(NH2CH2C6H5)2(Si(C6H5)(CH3)2)I·1/3C5H12 (triclinic; P = 94.38(3), β = 96.30(2), γ = 101.52(2)°) indicates three crystallographically unique complexes form a clathrate with a pentane guest. |
