| الوصف: | The crystal and molecular structures of [M(α, 1,2-η-CPh3)(acac)][M = Pd (3a) or Pt (3b); acac = pentane-2,4-dionate) have been determined. The unit cell of each contains enantiomers of two crystallographically independent molecules which are very similar in structure. Crystals of (3a) are triclinic, space group F, with a= 14.99, b= 13.18, c= 11.33 A, α= 101.08, β= 90.54, γ= 115.48°, and Z= 4; R= 0.050 for 5 607 independent reflections. Crystals of (3b) are triclinic, space group F, with a= 14.94, b= 11.41. c= 17.15 A, α= 120.78, β= 122.03, γ= 90.13°. and Z= 4; R= 0.045 for 5 978 independent reflections. Both structures were solved using Patterson and Fourier methods. The structures of (3a) and (3b) are very similar; each has an approximately square-planar metal atom OO′-bonded to acac and η3-benzylically bonded to the CPh3 ligand with Pd–C(α) 2.104(7), Pd–C(1) 2.158(7), Pd–C(2) 2.202 A and Pt–C(α) 2.080 (19), Pt–C(1) 2.127(20), and Pt–C(2) 2.153(23)A. |
