  摘要：

  为了评估支持配体对SS键活化的影响，通过Cu（）的反应合成了一系列由各种β-二酮或苯胺亚胺配体（L）支撑的[Cu2（mu-eta2：eta2-S2）] 2+络合物I）具有S 8的前体LCu（CH（3）CN）。对于L =β-二酮戊二酸酯的情况，由于簇[Cu（SR）] 4的形成而使合成变得复杂，其中SR表示在次甲基的中心位置被硫官能化的配体。[Cu2（mu-eta2：eta2-S2）] 2+产物通过X射线晶体学，电子吸收和共振拉曼光谱进行了表征。Cu-S，Cu-Cu和SS距离与nu（SS）值之间的相关性已在先前描述的结合图的框架中进行了观察和解释（Chen，P .; Fujisawa，K .; Helton，ME; Karlin ，KD; Solomon，EIJ Am。Chem。Soc。2003，125，6394）。将这些数据与其他相关物种的数据进行比较，发现在由β-二酮戊二烯和苯胺基亚胺配体

  The reaction of P4 and S8 in an argon discharge has produced a number of new phosphorus sulfides for matrix infrared spectroscopy. Contrasting product yields with PH3, H2S, P4S10, and P4S3 in the discharge and OCS in the matrix, photolysis and annealing behavior, and shifts with S-34 and S-32/S-34 isotopic mixtures have characterized the PS, P2S, and PS2 molecules. Isotopic spectra show that P2S is a linear molecule like P2O and N2O and that PS2 is bent like PO2 and NO2. Secondary reactions have provided evidence for P2S4, PS2-, and P4S. Although sulfur atoms are less reactive than oxygen atoms, many of the same phosphorus species are produced.

  Sulfur vapor was seeded into a microwave-powered argon discharge and condensed at 12 K. Infrared spectra revealed sharp strong bands at 690.0, 676.2, 661.6, and 642,4 cm-1, which were also observed by thermal dissociation of S8 flowing in a quartz tube heated to 400-900-degrees-C. Increasing the sulfur concentration in the discharge favored the latter two relative to the former two absorptions. Enriched S-34 samples gave isotopic shifts for pure sulfur fundamentals and isotopic multiplets that identify these species. Sample annealing produced a strong S2 chemiluminescence and a sharp new 674.5-cm-1 band. This feature revealed a sharp 1/2/1/1/2/1 sextet with 50/50 S-32/S-34, which confirms the observation of C2-nu thiozone; similar multiplets were found for the 680.0- and 676.2-cm-1 bands. Calculations from four pairs of symmetrical isotopic nu-3 values gave 116 +/- 2-degrees for the valence angle. The 661.6- and 642.4-cm-1 absorptions behaved differently in the experiments and revealed isotopic multiplets appropriate for S4; these absorptions are assigned to two different open-chain S4 isomers. Weaker bands at 720.5 and 710.1 cm-1, which appeared on annealing, are assigned to (S2)2 dimer species.
