Abstract
An investigation of the crystal structure of tetramminopalladous chloride has considerable interest because of Werner's contention that compounds containing bivalent palladium (or platinum) possess a planar configuration consisting of four groups coordinated about the central palladium atom. The correctness of this assumption has been verified in the case of potassium chloroplatinite and palladite by the x-ray studies of Dickinson (1). Pauling (2) has shown theoretically that the bivalent transitional elements platinum, palladium, and nickel can form bonds directed toward the corners of a square. Recently Cox (3) has reported that tetramminoplatinous chloride, Pt(NH3)4Cl2·H2O, is in accord with Werner's viewpoint and has a structure closely similar to that of potassium chloroplatinite. The determination of the structure of tetramminopalladous chloride was undertaken to test Werner's assumption for a cation containing bivalent palladium. This palladium compound might reasonably be expected to have the same structure as Pt(NH3)4Cl2·H2O; it is shown in this paper that the structure is closely related to the potassium chloroplatinite structure but is based on a unit containing two molecules instead of one as reported by Cox for the platinum compound.
Tetramminopalladous chloride forms pale yellow tetragonal needles from a solution of diamminopalladous chloride in aqueous ammonia. In most cases the crystals we prepared developed prism faces belonging only to {110}.
