Abstract: The title compounds, {5-(dimethylamino)-2-[N-(4-methoxyphenyl)iminomethyl]phenyl}[N-(4-methoxyphenyl)-4-nitrosalicylaldiminato]palladium(II), [Pd(C₁₄H₁₁N₂O₄)(C₁₆H₁₇N₂O)], (I), and [4-(diethylamino)-N-(4-methoxyphenyl)salicylaldiminato]{2-[N-(4-methoxyphenyl)iminomethyl]-5-nitrophenyl}palladium(II) dichloromethane hemisolvate, [Pd(C₁₄H₁₁N₂O₃)(C₁₈H₂₁N₂O₂)]·0.5CH₂Cl₂, (II), both contain push-pull chromophores coordinated to Pd in a square-planar arrangement. In both compounds, the five-membered orthopalladated ring is essentially planar, while the coordinated six-membered ring is not. Deviations from a coplanar arrangement of the phenylene rings of the coordinated Schiff bases are observed in both (I) and (II) as a result of intramolecular steric interactions.

Formula: [Pd(C₁₄H₁₁N₂O₄)(C₁₆H₁₇N₂O)] and [Pd(C₁₄H₁₁N₂O₃)(C₁₈H₂₁N₂O₂)]·0.5CH₂Cl₂
