以[Cu（I）（L）NCMe] BF_4为前体，合成了cis-1，3，5-tris（cinnamylideneamino）hexane（L）的Cu（I）配合物，该配合物中引入了一个不稳定的乙腈配体，该配体可以交换得到一系列新的Cu（L）X配合物（X = Cl，Br，NO_2，SPh）. 1H NMR谱和X-射线结构的Cl，Br和NO2配合物显示L协调在一个对称的方式关于铜中心。配合物已被进一步采用紫外/可见光谱和循环伏安法进行了表征。CuLCl在0.51 V（vs. Ag/AgCl）处显示出电化学可逆的Cu（I/II）氧化还原对，而CuLNO 2络合物在0.41 V（vs. Ag/AgCl）处显示出类似的准可逆波。
Copper(I) complexes of the ligand cis-1,3,5-tris(cinnamylideneamino)cyclohexane (L) have been prepared from a versatile precursor complex, [Cu(I)(L)NCMe]BF4, which incorporates a labile acetonitrile ligand that can be exchanged to give a range of new Cu(L)X complexes (where X = Cl, Br, NO2, SPh). 1H NMR spectra and X-ray structures of the Cl, Br and NO2 complexes show L coordinated in a symmetric fashion about the copper centre. The complexes have been further characterised using UV/Visible spectroscopy and cyclic voltammetry. CuLCl shows an electrochemically reversible Cu(I/II) redox couple at 0.51 V (vs. Ag/AgCl) while the CuLNO2 complex shows an analogous quasi-reversible wave at 0.41 V (vs. Ag/AgCl).
