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 SnBun3H, 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).
氢化物α-P 4小号4(H)R(R = H,I,NMePh或SPH)已经通过的反应在溶液中制备α-P 4小号3我2或相应的α-P 4小号3(I)R含SnBu n 3 H,并通过31 P NMR光谱鉴定。这些化合物不稳定且未分离。从头几何的分子轨道计算已经进行了对α-P 4小号3 ħ 2,α-P 4小号3(NME 2)2和α-P4 S 3 H(NMe 2)。
