Abstract
As a major product from the reaction of PNP-nitrite [P = P(C6H5)3] with elementary sulfur or a PNP-polysulfide (PNP)2S12 in acetone under anaerobic conditions PNP-perthionitrite (PNPnitrosodisulfide) PNP-SSNO has been isolated. VIS/UV-spectra point to a thionitrate or perthionitrate as a precursor.
The structures of PNP-SSNO and of the product obtained on treating the perthionitrite with triphenylphosphane in acetonitrile, PNP -SNO (PNP-monothionitrite, PNP-nitrososulfide), have been elucidated through X-ray diffraction and independently from new chemical and NMRspectrometric arguments. PNP-SSN O crystallizes in the orthorhombic space group P ben with a = 11.843(3), b = 16.647(5), c = 15.556(4) Å , PNP -SNO in the triclinic group P1̄ with a = 10.525(3), b = 17.196(5), c = 9.451(3) Å , a = 95.22(3), β = 92.32(3), γ = 91.65(3)°.
