- 中文摘要: The monomeric rhenium(I) complex with bidentate telluroether ligand Re(CO)/sub 3/Br(PhTe(CH/sub 2/)/sub 3/ TePh) was accessible via reaction of the PhTe(CH/sub 2/)/sub 3/TePh with Re(CO)/sub 5/Br. This chelate complex crystallized in triclinic space group P.1bar. with a=9.390(5).ANG., b=10.961(3).ANG., c=11.849(4).ANG.,.alpha.=63.30(3).degree., .beta.=87.49(4).degree.,.gamma.=69.31(4).degree., V=1009.5(7).ANG./sup 3/, Z=2, R=0.033, and R/sub w/=0.034. Reaction of Re(CO)/sub 5/ Cl with NaTePh yielded the Re(I) species PhTeRe(CO)/sub 5/. This complex crystallized in triclinic space group P.1bar. with a=7.085(1).ANG., b=9.203(1).ANG., c=11.341(1).ANG.,.alpha.=107.24(1).degree., .beta.=100.56(1).degree.,.gamma.=96.47(1).degree., V=683.2(2). ANG./sup 3/, Z=2, R=0.027, R/sub w/=0.022. Reaction of PhTeRe(CO)/sub 5/ and(PhSe)/sub 2/ in THF at 65.degree.C yielded a product that was confirmed crystallographically to be the known species Re/sub 2/(.mu.-SePh)/sub 2/(CO)/sub 8/ (3), in which two phenylselenolate ligands bridge the two Re(I). Compound (3) crystallized in monoclinic space group P2/sub 1//n with a=7.210(2).ANG. b=18.862(6).ANG., c=9.083(3).ANG.,.beta.=107.48(3).degree., V=1178.2(7).ANG./sup 3/, Z=2, R=0.046, and R/sub w/=0.051 . Methylation of PhTeRe(CO)/sub 5/ with [ Me/sub 3/O ] [ BF/sub 4/ ] afforded Re(I) product [ (PhTeMe)Re(CO)/sub 5/ ] [ BF/sub 4/ ] . This monodentate telluroether species crystallized in monoclinic space group P2/sub 1//n with a=8.405(1).ANG., b=13. 438(3).ANG., c=15.560(2).ANG., .beta.=92.59(1).degree., V=1755.5(5).ANG./sup 3/, Z=4, R=0.035, and R/sub w/=0.035.
