- 中文摘要: The triligate trimetallic complexes, [ .lbrace.M(CO)/sub 5/.rbrace./sub 3/(Pf-Pf-Pf) ] and tetraligate tetrametallic complexes, [ .lbrace.M(CO)/sub 5/.rbrace./sub 4/(P-Pf/sub 3/) ] (M=Cr and Mo), were prepared from [ M(CO)/sub 6/ ] and the corresponding ligands in MeCN/CH/sub 2/Cl/sub 2/ promoted by Me/sub 3/NO at 0.degree.C. Crystals of trimer are monoclinic, space group P2/sub 1//n, with a=13.407(3), b=15.002(5), c=26.52(1).ANG.,.beta.=90.65(2).degree., Z=4, and R=0.060 for 2760 observed reflections. Crystals of tetramer are monoclinic, space group P 2/sub 1//c, with a=14.183(8), b=29.880(4), c=16.103(2).ANG., .beta.=94.98(3).degree., Z=4, and R=0.039 for 5014 observed reflections. Crystals of [ .lbrace.Mo(CO)/sub 5/.rbrace. /sub 4/(P-Pf/sub 3/) ] Mo are monoclinic, space group C2/c, with a=42.120(8), b=13.679(1), c=23.486(2).ANG., .beta.=92.14(1).degree., Z=8, and R=0.032 for 6897 observed reflections. Each phosphorus atom of the ligands is coordinated to the M(CO)/sub 5/ moiety in each title compounds. The geometry of the four metals is a distorted tetrahedron for the tetramers.
