Crystal of the complex crystallizes in hexagonal space group R-3, with a = b = 33.302(3) Å, c = 15.308(2) Å, α = β = 90°, γ = 120°, V = 14702(3) Å3, Z = 18, R1 = 0.0823, wR2 = 0.2064, S = 1.011. X-ray analysis indicates that the V atom in the complex is in an octahedral coordination environment, constructed by the phenolate O and thiadiazol N atoms of L, one oxido O atom, one bridging O atom, and one
新型双核氧化钒(V)络合物[V 2 O 2(μ-O)L 2(OEt)2 ],其中L是2,4-二溴-6-(5-甲基氨基-[1,3]的去质子化形式通过2-(3,5-二溴-2-羟基苄叉基)-N-甲基肼基碳硫代酰胺(HL')和VO(acac)2在乙醇中的反应制备,4]噻二唑-2-基)苯酚(HL)。配体L'在配位过程中经历环化反应,形成新的配体L。配合物的结构通过理化方法和单晶X射线测定来表征。络合物的晶体在六边形空间群R -3中结晶,其中a = b = 33.302(3)Å,c= 15.308(2)埃,α=β= 90°,γ= 120°,V = 14702(3)3,Ž = 18,- [R 1 = 0.0823,WR 2 = 0.2064,小号= 1.011。X射线分析表明,该配合物中的V原子处于八面体配位环境中,由L的酚盐O和噻二唑N原子,一个氧化O原子,一个桥接O原子和一个去质子化乙醇O原子构成。两个V原子之间的距离为3
