BIS(ACETATO-O)BIS(PYRIDINE-N)PALLADIUM(II) MONOHYDRATE AND BIS(ACETATO-O)BIS(DIETHYLAMINE-N)PALLADIUM(II)

The title complexes, [Pd(C2H3O2)(2)(C5H5N)(2)].H2O, (I), and [Pd(C2H3O 2)(2)(C4H11N)(2)], (II), are typical of metal acetates with additional N-donor coordination. In both structures, the central Pd atom has a c entrosymmetric square-planar environment. In the pyridine complex (I), carbonyl O atoms are involved in intermolecular O-H ... O hydrogen bo nds with water molecules and in the amine complex (II), they participa te in intramolecular N-H ... O hydrogen bonds. Owing to the latter, th e Pd-N bond lengths are different with values of 2.010 (4) for complex (I) and 2.066 (2) Angstrom for complex (II).
