In the title complex, [Pd(CH3COO)2(C10H9N3)], the PdII ion is four-coordinated in a slightly distorted square-planar environment by two pyridine N atoms of the chelating di-2-pyridyl­amine (dpa) ligand and two O atoms from two anionic acetate ligands. The dpa ligand coordinates the PdII atom in a boat conformation of the resulting chelate ring; the dihedral angle between the pyridine rings is 39.3 (2)°. The two acetate anions coordinate the PdII atom as monodentate ligands and are located on the same sides of the PdN2O2 unit plane. The carboxyl­ate groups of the anionic ligands appear to be delocalized on the basis of the C—O bond lengths. Two complex mol­ecules are assembled through inter­molecular N—H⋯O hydrogen bonds, forming a dimer-type species. Inter­molecular C—H⋯O hydrogen bonds further stabilize the crystal structure.
