Synthesis and X-ray crystal structures of acenaphthenequinone-based alpha-diimine palladium complexes and a novel V-shape tripalladium cluster

摘要

Partially fluorinated 1,4-Diazadiene (alpha-Diimine) ligand 3,5-CF3-BIAN (1) formed from 3,5-bis(trifluoromethyl)aniline and acenaphthenequinone was used in the synthesis of palladium dichlorido complex 2 and its mono methyl chlorido palladium complex 3. Both complexes as well as side products of the reaction with methyl lithium such as trans-bis(3,5-bis(trifluoromethyl)aniline complex 4 and an interesting mixed valent trinuclear V-shaped palladium cluster 5 with two bridging mu(2),eta(3) -N,CN' non-innocent BIAN ligands were structurally characterized by the single-crystal XRD method.
