Each Pt ion is further coordinated with four sulfur atoms to form a square pyramidal structure with the Gd as the apex. The intramolecular Gd-Pt distances are 3.605(6) and 3.631(6) Å. These are shorter than the sum of the atomic radii (4.10 Å) but longer than the covalent (3.32 Å) and ionic (3.15 Å) radius The first-sphere intermolecular Gd-Gd distances are 12.549(5), 14.264(6), and 14.62(6) Å.
