Abstract: | 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. |
