solid S 7 Se have been recorded both at room temperature and at low temperatures down to ~30 K. Abnormal half-widths of the low-temperature spectra compared with those of S 8 indicate that an ordered phase of S 7 Se does not exist. Simultaneous calculations of a valence forcefield for 32 S 8 , 34 S 8 and S 7 Se yielded a refined forcefield for elemental sulphur along with the forceconstants of SSe
摘要 固体 S 7 Se 的拉曼光谱在室温和低至 ~30 K 的低温下均已记录。与 S 8 相比,低温光谱的异常半宽表明 S 7 Se 的有序相不存在。32 S 8 、34 S 8 和S 7 Se 的价力场的同时计算产生了元素硫的精细力场以及SSe 键和SSeS 角变形的力常数。对于所有三个分子,观察到的频率都在 0.5% 以内。

The recently reported hexasulfido complex ZnS6(TMEDA) is a potent polysulfide transfer agent as demonstrated by its ability to convert (C5H5)(2)TiCl2 into (C5H5)(2)-TiS5. More interesting is the use of the zinc complex to transfer an intact. S-6 Unit as established with the ''chalcogenospecific'' synthesis of 1,2-Se2S6. 1,2-Se2S6 is a rare example of easily prepared stable sulfur selenide available in isomeric purity.
