The hydrides α-P4S4(H)R (R = H, I, NMePh or SPh) have been prepared in solution by the reaction of α-P4S3I2 or of the corresponding α-P4S3(I)R with Sn-n-Bu3H, and identified by 31P NMR spectroscopy.The compounds were unstable and not isolated.Ab initio molecular orbital calculations of geometry have been carried out for α-P4S3H2, α-P4S3(NMe2)2 and α-P4S3H(NMe2).

P4S3 (1) reacts with organic disulphides RSSR under glass-filtered u.v. irradiation to give at first β-P4S3(SR)2 (2) and then α-P4S3(SR)2 (3) (R = Me, Et, or Ph), identified in the product mixtures by their 31P n.m.r. spectra.The identities of β-P4S3(SPh)2 and α-P4S3(SR)2 (R = Et or Ph) have been confirmed by the preparation of products with the same spectra by substitution reactions of β-P4S3I2 or α-P4S3I2 respectively.The 31P n.m.r. spectrum of β-P4S3I2 is reported.
