| Popis: | Doubly cyclopalladated mixed chelates of the type [Pd2L(-2H)(β-diket)2] derived from N,N′-diethylbenzene-l,3- dicarbaldimine (L) and the unsymmetrical β-diketones (Hβ-diket) benzoyltrifluoroacetone (HBTA), benzoylacetone (HBA) and thenoyltrifluoroacetone (HTTA) have been synthesized and characterized. The crystal structure of [Pd2L(−2H)(BTA)2] is reported. The complex C32H26N2O4F6Pd2 crystallizes in the triclinic space group P with a=10.872(1), b=11.915(1), c=13.525(1) A, α= 101.74(1), β=112.78(1), γ=97.77(1)°, V=1537.5(7) A3 and Z=2. The structure was solved by direct methods and refined by block-diagonal least-squares method to R=0.034 and Rw=0.037 based on 3535 observed reflections with I>3σ(I). |
