Abstract
Abstract The Pd(II) bis(benzonitrile) complex [Pd(PhCN)2Cl2] reacted with a mixture of 2-hydroxy-3-methoxybenzaldehyde, 1,3-diaminopropane, and triethylamine in acetonitrile to produce [Pd(L1)Cl] (HL1 = (E)-2-(((3-aminopropyl)imino)methyl)-6-methoxyphenol) (1), which contains an imine–amine-type macrocyclic ligand and a chloro ligand. Complex 1 was converted into a cyclohexane-like palladacycle, [Pd(NH2CH2CH2CH2NH2)Cl2] (2), when heated in acetonitrile at 80 °C for 60 h. The palladium compartment complex [Pd(L2)] (H2 L2 = N,N′-bis(3-methoxysalicylidenimino-1,3-diaminopropane) (3) was obtained from the free bis(imine) ligand (H2L2) and [Pd(PhCN)2Cl2] or Pd(OAc)2 in methanol. All complexes were structurally characterized by X-ray diffraction. Complex 3 is the first structurally characterized palladium compartment complex, in which the compartment ligand has an inner N2O2 and an outer O2O′2 compartments. The coordination geometry of the palladium metal in all complexes (1–3) can be best described as square-planar.
