环己基甲荒酸六氢吡啶盐与氯化铜反应,产物经二硫化碳重结晶,得四核铜原子簇化合物Cu_4(c-C_6H_(11)CSS_2)_4,用X射线单晶衍射法测定了它的晶体结构,其空间群为C_(4h)~4-P4_2/n晶胞参数a=b=15.125(5)(?),c=8.514(2)(?),α=β=γ=90°,V=1948(1)(?)~3,Z=2,929个衍射点参与修正,R=0.040.分子中Cu_4呈变形四面体构型。产物形成时,c-C_6H_(11)CSS~-与Cu~(2+)有氧化-还原反应发生。文章对产物形成的机理作了探讨。
Cyclohexylcarbamates were reacted with cupric chloride, and the product was recrystallized from carbon disulfide to obtain Cu_4 (c-C_6H_ (11) CSS_2) _4, a tetranuclear copper cluster compound, which was characterized by X-ray single crystal diffraction (4) ~ 4-P4_2 / n unit cell parameters a = b = 15.125 (5) (?), C = 8.514 °, V = 1948 (1) (?) ~ 3, Z = 2,929 diffraction points were involved in the correction, R = 0.040. Cu_4 in the molecule was deformed tetrahedron. At the time of product formation, c-C_6H_ (11) CSS ~ - and Cu ~ (2+) oxidation-reduction reaction occurred. The article discusses the mechanism of product formation.
