Resumo
The reaction of Tl(C6F5)2Cl or Tl(C6F5)3(diox) (diox=1,4 dioxane) with bidentate ligands (L=PPh2CH2PPh2, (O)PPh2CH2PPh2(O) or (S)PPh2CH2PPh2(S)) gives Tl(C6F5)2ClL or Tl(C6F5)3L, respectively. Displacement of chloride gives new cationic or neutral complexes, [Tl(C6F5)2{(O)PPh2CH2PPh2(O)}]+BF4 - or [Tl(C6F5)2(acac){(O)PPh2CH2PPh2(O)}] (acac=acetylacetonate), respectively. The structure of the latter was determined by single-crystal X-ray diffraction at 143 K. Crystals are monoclinic, space group P21/n, a =12.733(3), b=23.717(8), c=14.981(4) Å, β=110.37(3)°, Z=4 and R(F)=0.046. The structure forms a chain polymer. © 1994.
