Abstract The crystal structure, electrochemical behaviour and spectroscopic properties (FT-IR, UV–vis and EPR) of the mononuclear complex [Cu(HPClNOL)(CH3CN)](ClO4)2 1, are reported. The new tetradentate ligand, HPClNOL, 1-(bis-pyridin-2-ylmethyl-amino)-3-chloropropan-2-ol, reacts with 1 equiv. of [Cu(OH2)6](ClO4)2, in methanol, to give 1, which crystallizes as blue monoclinic crystals, space group
摘要 报道了单核配合物 [Cu(HPClNOL)(CH3CN)](ClO4)2 1 的晶体结构、电化学行为和光谱性质(FT-IR、UV-vis 和 EPR)。新的四齿配体 HPClNOL、1-(双-吡啶-2-基甲基-氨基)-3-氯丙-2-醇与 1 当量反应。[Cu(OH2)6](ClO4)2,在甲醇中,得到 1,结晶为蓝色单斜晶体,空间群 P21/c,a=14.906(3) A, b=11.371(2) A, c =14.113(3) A,β=103.86(3)°,V=2322.4(8) A3 和 Z=4。在图1中,铜心是五坐标的,呈现出扭曲的四角锥几何形状。电子光谱表明,在乙腈中,铜原子变为六配位 (λmax(e) 621 nm (87 dm3 mol−1 cm−1)。1 在纯乙腈中的冷冻溶液 EPR 光谱 (A‖=190 G, g‖ =2。24) 和 1 在乙腈/四丁基高氯酸铵溶液 (A‖=185
