摘要:
The title compounds, [N,N'-bis (2-pyridylcarbonyl)propane-1,3-diaminato-kappa(4)N]palladium(II) monohydrate, [Pd(C15H14N4O2)] . H2O, and [N,N'-bis(2-pyridylcarbonyl)propane-1, 3-diaminato-kappa(4)N] nickel(II) monohydrate, [Ni(C15H14N4O2)] . H2O, were investigated by means of X-ray diffraction and high-resolution NMR. The Pd-II and Ni-II ions have regular and distorted square-planar coordination geometries, respectively. Libration of the propanediyl chains in these complexes was observed in both the crystalline and solution states.
