Resumo
Structural studies on the two binuclear cyclometallated compounds [Pd(C-2,N-bzan)(mu-N-3)](2) (1) and [Pd(C-2,N-bzan)(mu-Pz)](2) (2) (bzan = N-benzylideneaniline) have been carried out in this work. In both compounds, C-H center dot center dot center dot pi interactions play an important role in the molecular self-assembly. In complex 1, ortho-CH bonds from bzan moiety interact with the cyclopalladated ring at a distance of C-bzan center dot center dot center dot C-g 3.448(6) angstrom, providing a new structural evidence for the metalloaromaticity of the cyclometallated ring.
