{1,2-Bis[N-(4-methylphenyl)imino-N]acenaph-thene}(η²-maleic anhydride)palladium(0)

The title compound, [Pd(C₂₆H₂₀N₂)(C₄H₂O₃)], displays trigonal coordination of palladium by both nitrogen atoms and the double bond of maleic anhydride. The spatial arrangement of N-aryl groups in the title compound, compared to a sterically more congested analogue, explains satisfactorily its enhanced reactivity towards organic substrates. The crystal packing involves weak C—H...O and C—H...π interactions.
