The crystal structures of Cu(n-Bu-3-2)ClO4 (10), Cu(H-3-3)BF4·EtOH (11b), and Cu(Me-3-3)ClO4 (12a) were determined by the single-crystal X-ray diffraction method. The detailed analysis of the structures and reflectance spectra led to the same conclusion as Kida’s one in assigning the near-ultraviolet absorption band. That is, the absorption was ascribed to the charge transfer (CT) from the bridging oxygen’s
通过使用一系列与N,N-二烷基二氨基醇Cu2R2N(CH2)mNH(CH2)nO}2X的双核铜(II)配合物,重新研究了二烷氧基桥连双核铜(II)配合物的近紫外吸收带特性'2(简写为Cu(Rmn)X', X' = ClO4, BF4)。在这项研究中,包括 10 种新化合物在内的 18 种配合物被制备并根据 Kida 的分类分为两种类型,即 A 型和 B 型,基于它们的磁化率(80-300 K)和反射光谱的温度依赖性。Cu(n-Bu-3-2)ClO4 (10)、Cu(H-3-3)BF4·EtOH (11b) 和 Cu(Me-3-3)ClO4 (12a) 的晶体结构由下式确定单晶X射线衍射法。对结构和反射光谱的详细分析得出了与 Kida 在分配近紫外吸收带方面相同的结论。也就是说,吸收归因于从桥接氧的非键轨道到空铜 d 轨道的电荷转移 (CT)。另一方面哈...
