Reaction of tetrakis(acetonitrile)copper(I) perchlorate ([Cu(NCCH3)4][ClO4]), tris-1-ethyl-4-methylimidazolylphosphine (T1Et4MeIP) (1) and 3-hydroxyflavone (flavH) under ambient conditions produces an in-situ generated flavonol bound copper(II) complex, which converts to a stable green complex that formulates to [Cu(T1Et4MeIP)(flav)][ClO4] (2). The crystal structure of 2 was determined by X-ray diffraction
摘要 四(乙腈)高氯酸铜(I) ([Cu(NCCH3)4][ClO4])、tris-1-ethyl-4-methylimidazolylphosphine (T1Et4MeIP) (1) 和 3-羟基黄酮 (flavH) 在环境条件下的反应产生原位生成的黄酮醇结合铜 (II) 络合物,该络合物转化为稳定的绿色络合物,形成 [Cu(T1Et4MeIP)(flav)][ClO4] (2)。2 的晶体结构由 X 射线衍射确定并在三斜晶系 (P 1 ¯ ) 中结晶,晶胞尺寸为 a = 14.537(15) A, b = 15.794(14) A, c = 17.044(17) A, α = 65.58(3)˚, β = 86.80(5)˚, γ = 73.34(4)˚, V = 3376(6) A3 和 Z = 2. 而五配位铜 (II) 配合物是稳定的在固态环境条件下,在分子氧的存在下,它在光解
