Abstract

By a high-temperature reaction of rhenium(III) iodide and red phosphorus with an excess of sodium cyanide followed by recrystallization from an aqueous solution a new tetrahedral [{Re₄(PO)₄}(CN)₁₂]^8– anionic cluster complex is obtained. It is isolated as a salt of the composition Na₈[{Re₄(PO)₄}(CN)₁₂] 18H₂O·MeOH. The structure of the obtained compound is determined by X-ray crystallography. The compound crystallizes in the monoclinic crystal system, P2₁/n space group, unit cell parameters a = 26.826(3) Å, b = 11.4975(12) Å, c = 29.141(3) Å, β = 97.879(2)°, V = 8903.2(16) Å³, Z = 8.

含{Re4(PO)4}4+核的铼四面体簇复合体的合成与结构

摘要

通过碘化铼 (III) 和红磷与过量氰化钠的高温反应，然后从水溶液中重结晶形成新的四面体 [{Re ₄ (PO) ₄ }(CN) ₁₂ ] ^8–阴离子簇配合物获得。它被分离为组成为 Na ₈ [{Re ₄ (PO) ₄ }(CN) ₁₂ ] 18H ₂ O·MeOH的盐。所得化合物的结构由X射线晶体学确定。化合物在单斜晶系中结晶，P 2 ₁ / n空间群，晶胞参数a = 26.826(3) Å, b  = 11.4975(12) Å, c  = 29.141(3) Å, β = 97.879(2)°, V  = 8903.2(16) Å ³ , Z  = 8。
