Not 15, but 16 sulfur atoms are found in [NH 4 ] 3 [Ir(S 4 )(S 6 ) 2 ], which was first reported as “[NH 4 ] 3 [IrS 15 ]” in 1904. This was determined by comparing the results of the crystal structure analysis (structure shown on the right) with the optical goniometric data reported in the original work. [NH 4 ] 3 [Ir(S 4 )(S 6 ) 2 ] spontaneously resolves upon crystallization. Therefore, these enantiomeric crystals were available a decade before Werner first separated optically active inorganic complexes.
