Abstract
This contribution presents the results of a single crystal X-ray diffraction study of three ammine complexes of bivalent platinum and palladium: [Pt(NH3)4](NO3)2, [Pd(NH3)4](NO3)2 and [Pd(NH3)4]F2·H2O. The first two compounds are isostructural; metal atoms are located on inversion centers, all other atoms are in general positions. A three-dimensional framework is built from planar-square complex cations and nitrate ions joined by N-H…O hydrogen bonds. In [Pd(NH3)4]F2·H2O, palladium atoms, as in the previous cases, are located on inversion centers, while oxygen atoms of water molecules are on the two-fold symmetry axis. A network of strong N-H…F and O-H…F hydrogen bonds linking the cations, anions, and crystallization water molecules is present in the structure.
