Bis(acetato-O)bis(pyridine-N)palladium(II) Monohydrate and Bis(acetato-O)bis(diethylamine-N)palladium(II)

Abstract

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