Abstract

The condensation of trinuclear rhenium bromide with lead sulfide yields the (H₉O₄)₂Re₆S₆Br₈ octahedral cluster complex isolated from the HBr/EtOH mixture in the form of the acid. (H₉O₄)₂[Re₆S₆Br₈] crystallizes in the P2₁/c space group, a = 9.2010(2) Å, b = 9.1508(2) Å, c = 17.3759(3) Å, γ = 101.817(1)°. Thermal decomposition of the complex at a moderate temperature (350 °C) results in a metastable Re₆S₆Br₆ compound, which is not formed in the ternary Re–S–Br system at high temperatures. This compound is X-ray amorphous; its structure is determined based on the X-ray photoelectron and Raman spectroscopy data.

摘要

三核溴化铼与硫化铅缩合产生以酸形式从HBr/EtOH混合物中分离出来的(H ₉ O ₄ ) ₂ Re ₆ S ₆ Br _{8八面体簇络合物。}(H ₉ O ₄ ) ₂ [Re ₆ S ₆ Br _{8 ] 在}P 2 ₁ / c空间群中结晶， a  = 9.2010(2) Å, b  = 9.1508(2) Å, c  = 17.3759(3) Å, γ = 101.817(1)°。该络合物在中等温度（350 °C）下热分解，产生亚稳态 Re ₆ S ₆ Br ₆化合物，该化合物在三元 Re-S-Br 体系中不会在高温下形成。该化合物是X射线无定形的；其结构是根据X射线光电子和拉曼光谱数据确定的。
