The crystal is built up of nearly octahedral Ir(NH3)5-Cl2+ cations and
planar PtCl42- anions, each of m symmetry. The coordination of these
ions is 6/6. They are stabilized by electrostatic interactions and the
re are hydrogen bonds (N-H...Cl) which take part in the packing of the
structure to form a three-dimensional network.
