heterocyclic ligands binding in the common N,N′-exo-bidentate mode; however, the shape and geometry of the inner Cu4 moiety is remarkably different, as highlighted, for example, by the absolute values of the 1,2 and 1,3 (non-bonding) Cu⋯Cu interactions. These polynuclear copper(I) pyrazolate complexes catalyse the conversion of alkenes into the corresponding cyclopropane derivatives with interesting diastereomeric
We prepared a series of copper(I) polynuclear complexes bridged by three different alkyl substituted pyrazolate anions. From X-ray analysis, these differences reflected their molecularstructures. These structural changesalso reflected some properties in their IR, far-IR, UV-vis, and NMR spectra.
我们制备了一系列由三种不同的烷基取代的吡唑酸阴离子桥接的铜 (I) 多核配合物。从 X 射线分析来看,这些差异反映了它们的分子结构。这些结构变化也反映了它们的红外、远红外、紫外可见和核磁共振光谱的一些特性。
