Metal Sulfur Nitrogen Compounds. 16. Products of the Reaction of Lead- and Tin Salts with S4N4. Structures of PbN2S2 · NH3, PbN2S2, and SnCl4 · 2S4N4PbN2S2 · 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.
Notes:
PbN2S2 · NH3 kristallisiert monoklin, Raumgruppe P21/a mit a = 5,671 Å, b = 16,123 Å; c = 6,102 Å, β = 95,12°, Z = 4, PbN2S2 dagegen orthorhombisch, Raumgruppe P212121 mit a = 4,375 Å, b = 7,654 Å, c = 12,274 Å, Z = 4. Die ebenen fünfgliedrigen PbN2S2-Ringe beider Verbindungen unterscheiden sich nur unwesentlich. Bei PbN2S2 · NH3 ist an Pb zusätzlich noch ein NH3-Molekül senkrecht zur Ringebene gebunden.Von der schon lange bekannten Additionsverbindung SnCl4 · 2S4N4 konnte ebenfalls die Struktur bestimmt werden: orthorhombisch, Raumgruppe Pc21b mit a = 11,467 Å, b = 11,995 Å, c = 12,374 Å, Z = 4. Sn ist 6fach koordiniert, die beiden S4N4-Ringe sind über je ein N-Atom in Transstellung an Sn gebunden.
