dpc and dac with copper(II) chloride gives compounds [Cu(dpc)(H2O)2]Cl2 (1) and [Cu(dac)(H2O)2]Cl2 (3) with similar crystal structures. Compounds 1 and 3 were used as precursors in the synthesis of Cu(II)/Mn(II) complexes 2, 4a and 4b. Prepared complexes were characterized by IR spectroscopy, elemental analysis and their crystal structures were determined using single crystal X-ray analysis. Compounds
的两种衍生物cyclam(cyclam 与丙基或烯丙基(丙-2-烯-1-基)对反式位置的氮原子的取代基= 1,4,8,11-四氮杂),即1,8-二丙基-1-制备了,4,8,11-四氮杂环十四烷( dpc )和1,8-二烯丙基-1,4,8,11-四氮杂环十四烷( dac ),并用IR、1 H NMR和13 C NMR光谱对其进行了表征。的反应DPC和DAC与铜(II)氯化物得到化合物[铜(DPC)(H 2 O)2 ]氯2(1)和[铜(DAC)(H 2 O)2]Cl 2 ( 3 ) 具有相似的晶体结构。化合物1和3用作合成 Cu(II)/Mn(II) 配合物2、4a和4b 的前体。制备的配合物通过红外光谱、元素分析进行表征,并使用单晶 X 射线分析确定其晶体结构。化合物4a和4b是多晶型物,均在单斜晶系中结晶,其晶体结构的主要区别在于链内金属中心的空间排列。此外,对双金属配合物2和4a进行的磁化率测量和破坏对称
