Copper(Ⅱ) complexes of two types, (l) [Cu(A)(NN)(H20)] and [Cu(A)(NN)(Cl04)]; (2) [Cu(A)(N)], where A=N-acetoacetylglycinate(naag); NN=1,10-phenanthroline(phen) , 2,2'-bipyridine (bipy) , N,N'-dimethylethylenediamine(dmen); N =pyridine(py), 3-methylpyridine(3Mpy), 4-methylpyridine (4Mpy), 4-aminopyridine (4apy), 4-dimethylaminopyridine (4dMapy), N-methylimidazole (NMIm), imidazole (ImH), 2-methylimidazole (2MlmH), 4-methylimidazole (4MImH), have been synthesized and characterized by elemental analyses, and IR, UV-VIS, and EPR spectroscopic measurements.
By single-crystal X-ray diffraction method, the crystal and molecular structures of [Cu(naag)(phen)(H20)]3H20, [Cu(naagCH2CH3)(phen)(CIO4)] have been determined. The crystal data of these two complexes are described below:
(1) [Cu(naag)(phen)(H20)]3H2O crystallizes in the triclinic, space group P1 with a=9.056(2)A, b=11.249(4)A, c=11.632(5)A, α=115.33(3)°, β=103.41(2)°, γ=94.09(2)°, V =1022.3(7)A3, Z=2, R=0.041, Rw=0.046.
(2) [Cu(naagCH2CH3)(phen)(Cl04)] crystallizes in the triclinic, space group P1 with a=9.249(4)A, b=10.846(4)A, c=12.216(5)A, α=110.94(1)°, β=105.15(1)°, γ=96.30(1)°, V =1076.3(4)A3, Z=2, R=0.043, Rw=0.057.
The solid state LF spectra of the complexes were deconvoluted into Gaussian component bands. The results were employed to interpret the electronic and bonding properties of the Cu(Ⅱ) complexes. In the meantime, the sequences of d orbitals were assigned as following:
(1) [Cu(A)(NN)(H2O)] dxy>>dz2>dx2-y2, dxz>dyz
(2) [Cu(A)(NN)(Cl04)] dxy>>dz2>dx2-y2, dxz>dyz
(3) [CU(A)(N)] dx2-y2>>dz2>dxy>dyz>dxz
