摘要：

The exchange couplings in [{Dy(hfac)(3)}(2)Cu(dpk)(2)] and [{Dy(hfac)(3)}(2)-Ni(dpk)(2)(py)(2)] (Hdpk = di-2-pyridyl ketoxime) were precisely evaluated by high-frequency electron paramagnetic resonance and pulsed-field magnetization studies, giving J(Dy-Cu)/k(B) = -0.126 K and J(Dy-Ni)/k(B) = +0.031 K.
