Synthese und Kristallstruktur des Anions [P₄S₉N]⁻ / Synthesis and Crystal Structure of the Anion [P₄S₉N]⁻

[(nC 3 ,H 7 ) 4 N] + [P 4 S 4 N] − 1 has been synthesized from P 4 S 10 and [(nC 3 H 7 ) 4 N] + [S 2 P(N 3 ) 2 ] − . 1 crystallizes in the space group P2 1 /c with a = 936.9(2), b = 1731.1(3), c = 1694.6(3) pm , β = 93.41(2)° and Z = 4. The [P 4 S9N]~ anion has an adamantane-like structure, with bridging rather than terminal nitrogen.
