Two orthopalladated chromophores.
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.
