碩士 === 國立臺灣師範大學 === 化學系 === 84 === The derivaties of the Metal carbonyl cluster, [{Ru3(CO)11}2( trans-bdpe)](1), [Os3(CO)10(dppf)](2),[Os3(CO)8(CL)3(cis-bdpe) ](3),[Os3(CO)7(Ph)(CH3C(CH2PPh2)(CH2PPh)(CH2PC6H4)](4). (1) and (2) were synthesized by chemical oxidation method with TMNO as initiator at 0. (3) and (4) were synthesized by thermolytic method. Complexes have been identified by IR, EA and P-NMR,and their structures were undertaken by X-ray diffraction method. The red crystal of (1) crystallized in triclinic space group P1, a= 10.34(2), b=12.223(2), c= 12.743(3),final Rf= 0.023 for 4813 observed reflections The molecule has a monosubstituted biunit structure with an inversion centerat the middle point of the carbon-carbon double bond. The red crystal of (2) crystallized in orthorhombic space group Pbcn,a=16.179(2), b=16.850(3), c=18.247(3), final Rf=0.028 for 4368 observed re-flections. The molecule has a bridged ring with a two-fold axisthrough the Fe atom and Ru atom. The red crystal of (3) crystallized in monoclinic space group P21, a=12.686(4), b=14.681(4), c=15.683(3). Rf=0.066 for 5022 observed reflections.The molecule has a five-memberd chelating ring and a bridged six-membered ring. The red crystal of (4) crystallized in monoclinic space group P21/c,a=9.692(4), b=21.477(4), c=25.361(7).final Rf=0.104 for 5807 observed reflect-ions. The molecule are coordinated by an axial phosphorous atom, two equator-ial phosphorous atoms, a discrete phenyl group, a phenyl group attached toa phosphorous atom and seven carbonyl group.
