(Di-2-pyridylamine-[bold kappa]2N,N')(naphthalene-2,3-diolato-[bold kappa]2O,O')palladium(II) monohydrate and (di-2-pyridylamine-[bold kappa]2N,N')(3-oxidonaphthalene-2-carboxylato-[bold kappa]2O,O')palladium(II)

Abstract: In the title complexes, [Pd(C10H6O2)(C10H9N3)]·H2O, (I), and [Pd(C11H6O3)(C10H9N3)], (II), the PdII centers have a distorted cis-square-planar geometry. In (I), the PdII 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. In (II), the PdII atom is coordinated to two N atoms of the DPA ligand, one carboxylate O atom and one oxide O atom from the 3-oxidonaphthalene-2-carboxylate (NC) ligand. The dihedral angle between the planes of the two pyridine rings of DPA in (I) is 16.20  (12)° and that in (II) is 29.45  (10)°. In (I), the molecules are linked by N-H...O and O-H...O hydrogen bonds to generate centrosymmetric dimers. In (II), molecules are linked by N-H...O and C-H...O hydrogen bonds to generate spirals.

Formula: [Pd(C10H6O2)(C10H9N3)]·H2O and [Pd(C11H6O3)(C10H9N3)]
