ResumoBis(glyoximato)Pd(II), (H2C2OOH)2Pd, crystallizes in the triclinic system with two molecules per unit cell and belongs to space P1−. Unit-cell parameters are: ao = 3.5581 Å, bo = 7.7720 Å, co = 14.0172 Å, α = 89°33′, gb = 91°39′, γ = 89°54′. The structural analysis of this complex, based on all the reflexions accessible with Cu Kα radiation and measured by an automatic diffractometer (final R value 0.046), shows that in the two crystallographically non equivalent molecules Pd atoms coordinate four N atoms on a plane and that the whole molecules are planar. The intramolecular hydrogen bonds O-H- - -O, have to be considered asymmetric. Pd atoms are not interested in any contact, while some intermolecular contacts between C and O atoms are worth recording.
