susceptibility measurements, ligand field spectra, EPR spectra, thermal studies and X-ray diffraction spectra. Vibrational spectra indicate coordination of amide and carboxylate oxygens of the ligands giving a MO(4) square planar chromophore. Ligand field and EPR spectra support square planar geometry around Cu(II). [Cu(L(1))] complex has the maximum activation energy and [Cu(L(3))] complex has the minimum activation
Cu(II)与N,N'-双(3-羧基-1-氧代丙烷基)-1,2-乙二胺(C(10)H(16)N(2)O(6),L(1)的配合物),N,N'-双(3-羧基-1-氧代丙烷基)-1,2-苯二胺(C(14)H(16)N(2)O(6),L(2)),N,N '-双(2-羧基-1-氧代菲烯基)-1,2-苯二胺(C(22)H(16)N(2)O(6),L(3))和N,N'-bis(3 -羧基-1-氧代丙-2-烯基)-1,2-苯二胺(C(14)H(12)N(2)O(6),L(4))已制备并通过振动,元素分析表征光谱,磁化率测量,配体场光谱,EPR光谱,热学和X射线衍射光谱。振动光谱表明配体的酰胺和羧酸氧的配位产生MO(4)方形平面发色团。配体场和EPR光谱支持Cu(II)周围的正方形平面几何形状。
