本文合成和表征了两种新的杂双核配合物:[Cu(oxdn)Ni(tmn)_2(ClO_4)_2(1)和[Cu(oxdn)Ni(tmd)_2](ClO_4)2(2),oxdn代表N,N'-双(3-氨丙基)草酰胺根阴离子;tmn为N.N.N'-四甲基乙二胺;tmd表示1.3-丙二胺。测定了配合物(1)的变温磁化率(4~300K),其数值用最小二乘法和从自旋哈密顿算符H=-2JS_1·S_2导出的磁方程拟合,求得交换积分J=-118.8cm ̄(-1)。文中还用Kahn理论解释了这种反铁磁自旋交换作用。
In this paper, two new heterobinary complexes were synthesized and characterized: [Cu (oxdn) Ni (tmn) 2 (ClO_4) _2 (1) and [Cu (oxdn) Ni (tmd) _2] (ClO_4) 2 Oxdn represents N, N’-bis (3-aminopropyl) oxalate anion; N. N’-tetramethylethylenediamine; tmd represents 1.3-propylenediamine. The temperature-dependent magnetic susceptibility (4 ~ 300K) of the complex (1) was measured. The values were fitted by the least square method and the magnetic equation derived from the spin Hamiltonian H = -2JS_1 · S_2. The exchange integral J = -118.8 cm ~ (-1). The Kahn theory is also used to explain this antiferromagnetic spin exchange.
