Application of 499-40-1. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.
(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(C10H6O 2)(C10H9N3)]¡¤H2O, (I), and [Pd(C11H6O3)(C10H 9N3)], (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.
