Metall-Schwefelstickstoff-Verbindungen. 16. Reaktionsprodukte von Blei- und Zinnsalzen mit S4N4 Die Strukturen von PbN2S2 · NH3, PbN2S2 und SnCl4 · 2S4N4

Metal Sulfur Nitrogen Compounds. 16. Products of the Reaction of Lead- and Tin Salts with S₄N₄. Structures of PbN₂S₂ · NH₃, PbN₂S₂, and SnCl₄ · 2S₄N₄ PbN₂S₂ · NH₃ is monoclinic, P2₁/a, a = 5.671, b = 16.123, c = 6.102 Å, β = 95.12°, Z = 4, PbN₂S₂, however, orthorhombic, P2₁2₁2₁, a = 4.375, b = 7.654, c = 12.274 Å, Z = 4. The planar five-membered PbN₂S₂ rings in both compounds show no remarkable differences. In PbN₂S₂ · NH₃, the NH₃ molecule is bound to Pb perpendicularly to the plane of the ring. The structure of the long known addition compound SnCl₄ · 2S₄N₄ was determined. It is orthorhombic, Pc2₁b, a = 11.467, b = 11.995, c = 12.374 Å, Z = 4. Sn shows sixfold coordination, the two S₄N₄ rings are attached to Sn trans to each other via a N atom.
