S4N4 und seine Derivate: α-FeCl3 · S4N4, ein Übergangsmetallkomplex mit dem S4N4-Ligand / S4N4 and its Derivatives: α-FeCl3 · S4N4, a Transition Metal Complex with the S4N4 Ligand

Abstract

The adduct α-FeCl3 · S4N4 has been prepared from FeCl3 and S4N4 in CCl4. The new compound crystallizes in the monoclinic space group P 21/c with Z = 4 and lattice parameters a = 6.360(2), b = 13.066(4), c = 12.686(5) Å, and β = 99.43(3)°. An X-ray analysis shows that the S4N4 ring is bonded via one of its nitrogen atoms to the iron atom of the FeCl3 group and that the four ligand atoms around the iron atom form a tetrahedron. The structure of the complex is similar to the known structure of BF3 · S4N4
