文摘

The complex Na₃(NH₄)₂[Ir(SO₃)₂Cl₄]·4H₂O was examined with single crystal X-ray diffraction and IR spectroscopy. Crystal data: a = 7.3144(4) ?, b = 10.0698(5) ?, c = 12.3748(6) ?, β = 106.203(1)°, V = 875.26(8) ?3, space group P2₁/c, Z = 2, d _calc = 2.547 g/cm3. In the complex anion two trans SO ₃ 2? groups are coordinated to iridium through the S atom. The splitting of O-H bending vibrations of crystallization water molecules and N-H ones of the ammonium cation is considered in the context of different types of interactions with the closest neighbors in the structure.
