报道2个具有三足四齿配体,三(2-甲基吡啶)胺(缩写TPA)的单、双核镍(Ⅱ)配合物.X射线晶体结构分析结果表明,双核镍配合物(1)晶体(C_(36)H_(36)N_8Ni_2Cl_2)·11/6(ClO_4)·1/6(OH)·8/6(H_2O)属三方晶系,空间群为R-3,a=2.8425(4)nm,b=2.8425(4)nm,c=1.4385(5)nm,α=β=90.00°,γ=120.00°,Z=18,最终因子R=0.078,R_w=0.078.单核配合物晶体C_(20)H_(18)N_6NiS_2·0.5(H_2O),属三斜晶系,空间群P(?),a=0.9467(1)nm,b=1.5566(3)nm,c=1.5913(3)nm,α= 73.59(4)°,β=87.37(3)°,γ=76.27(2)°,Z=4,最终因子R=0.0784,R_w=0.238.双核配合物的变温磁化率(4～300K)数据表明,用最小二乘法进行理论拟会(H=-2JS_1·S_2),得出交换积分J=6.72cm~(-1),θ=-0.60cm~(-1),表明双核镍之间为弱的铁磁相互作用,分子间为弱的反铁磁相互作用.
Two single-binuclear nickel (Ⅱ) complexes with three-legged tetradentate ligands and tris (2-methylpyridine) amine (abbreviated TPA) were reported.The X-ray crystal structure analysis showed that the binuclear nickel complexes (1) (C_ (36) H_ (36) N_8Ni_2Cl_2) · 11/6 (ClO_4) · 1/6 (OH) · 8/6 (H_2O) belongs to the trigonal system with a space group of R-3 and a = 2.8425 ), b = 2.8425 (4) nm, c = 1.4385 (5) nm, α = β = 90.00 °, γ = 120.00 °, Z = 18, final factor R = 0.078, R_w = 0.078. Mononuclear complex crystals (20) H_ (18) N_6NiS_2 · 0.5 (H_2O) belongs to triclinic system with space group P (?), A = 0.9467 (1) nm, b = 1.5566 (3) nm and c = 1.5913 (3) nm, α = 73.59 (4) °, β = 87.37 (3) °, γ = 76.27 (2) °, Z = 4 and final factors R = 0.0784 and R_w = 0.238. 300K). The data show that the exchange integral J = 6.72cm -1 and θ = -0.60cm -1 are obtained by using the least squares method to simulate the theory (H = -2JS_1 · S_2) Weak interaction between the ferromagnetic, intermolecular weak anti-ferromagnetic interaction.
