(Di-2-pyridylamine-kappa2N,N')(naphthalene-2,3-diolato-kappa2O,O')palladium(II) monohydrate and (di-2-pyridylamine-kappa2N,N')(3-oxidonaphthalene-2-carboxylato-kappa2O,O')palladium(II).

In the title complexes, [Pd(C10H6O2)(C10H9N3)].H2O, (I), and [Pd(C11H6O3)(C10H9N3)], (II), the Pd(II) centers have a distorted cis-square-planar geometry. In (I), the Pd(II) atom is coordinated to two N atoms of the di-2-pyridylamine (DPA) ligand and two O atoms of the naphthalene-2,3-diolate (ND) dianion.
