- 中文摘要: Diphenyldichalcogenides (PhE)/sub 2/ (E=Te,Se) react with Fe(0)-phenylchalcogenolate [ PPN ] [ PhEFe(CO)/sub 4/ ] to yield the products of oxidative addition, Fe(II)-mixed- phenylchalcogenolate fac- [ PPN ] [ Fe(CO)/sub 3/(TePh)/sub n/(SePh)/sub 3-n/ ] (n=1,2). Reactions of [ PPN ] [ REFe(CO)/sub 4/ ] (E=Se,R=Me;E=S,R=Et) and diphenyldichalcogenides yielded ligand-exchange products [ PPN ] [ PhEFe(CO)/sub 4/ ] (E=Te,Se,S). The compounds [ Fe(CO)/sub 3/(TePh)(SePh)/sub 2/ ] /sup -/ (1) and [ Fe( CO)/sub 3/(TePh)/sub 2/(SePh) ] /sup -/ (2) crystallize in the isomorphous monoclinic space group C/sub (2/c)/, with a=32.035(8), b=11.708(6), c=28.909(6).ANG., Z=8, R=0.048, and R/sub w/=0.044 (1); with a=32.089(5), b=11.745(2), c=28.990(8).ANG., Z= 8, R=0.048, and R/sub w/=0.048 (2). The complexes (1) and (2) crystallize as discrete cations of PPN/sup +/ and anions of [ Fe(CO)/sub 3/(TePh)/sub n/(SePh)/sub 3-n/ ] /sup -/(n=1,2), and one half solvent molecule THF. The geometry around Fe(II) is a distorted octahedron with three carbonyl groups and three phenylchalcogenolate ligands occupying facial positions.
