The sulphenyl chloride, Ph2CNSCl, prepared in situ from Ph2CNSiMe3 and sulphur dichloride, has been employed in the synthesis of Ph2CNSNSO and Ph2CNSNSNSNCPh2 by reaction with Me3SiNSO and Me3SiNSNSiMe3, respectively.An X-ray structural determination of Ph2CNSNSO shows it to consist of a planar cis-trans chain.The crystals are triclinic and belong to the space group P1/, a = 9.9078(8), b = 10.0967(9), c = 15.1682(14) Angstroem, α = 78.646(7), β=71.065(7), γ = 63.449(7) deg, V = 1281.5(5) Angstroem3, Z = 4.The final R and Rw values were 0.033 and 0.027, respectively.The ?* ---> ?* excitation energies for the RSNSO and RSNSS chromophores are compared for different R groups and discussed in the light of MNDO calculations on the model compounds HSNSX (X = S, O).The thermal decomposition of both Ph2CNSNSO and Ph2CNSNSNSNCPh2 produced S4N4 and Ph2CO or (Ph2CN)2S, respectively.
