Abstract

The diazidodithiophosphate anion [PS 2 (N 3 ) 2 - ] can be isolated with a large cation as (Ph 4 As + ][PS 2 (N 3 ) 2 - ] (1). [PS 2 (N 3 ) 2 - ] is formed by the reaction of P 4 S 10 with NaN 3 in acetonitrile as a solvent. [(NCPS 2 ) 2 S 2 - ] results from the reaction of P 4 S 10 with NaCN in acetonitrile and is isolated as [(n-C 3 H 7 ) 4 N + H(NCPS 2 ) 2 S 2- ] (2). 1 crystallizes in the triclinic space group P1̄ with a - 1329.3(3), b = 1419.1(3),c = 2182.3(5) pm, α = 71.71(2), β = 87.21(2), γ = 84.97(2)° and Z = 6. Crystals of 2 are monoclinic, space group P2 1 /n, a - 1899.0(3), b - 949.0(2), c = 2128.4(5) pm, β = 112.90(2)°, Z = 4.
