Synthesis and crystal structure of [Pd{C6H4(CH2NHCH2Ph)-2-κ2C, N}(μ-I)]2

Abstract

The binuclear title complex, di-μ-iodido-bis(-{2-[(benzylamino-κN)meth-yl]phenyl-κC¹}palladium(II)), [Pd₂I₂(C₁₄H₁₄N)₂], was prepared by reaction of [Pd{C₆H₄(CH₂NHCH₂Ph)-2}(μ-OAc)]₂ with NaI. It crystallizes with one discrete mol-ecule in the asymmetric unit. The mol-ecule presents an iodide-bridged dimeric structure with a cisoid arrangement with respect to the C,N-cyclo-palladated ligands. Both Pd^II atoms have a slightly distorted square-planar coordination environment. Weak inter-molecular contacts of the type C-H⋯Pd seem to have a significant influence on the arrangement of the mol-ecules along the b axis in the crystal.

Keywords: C,N-cyclo­palladated complex; crystal structure; iodide bridge.
