【摘要】 利用柔性三脚架配体1,3,5-苯三乙酸(H3bta)与Ho(NO3)3?6H2O在水热条件下组装得到了一个具有三维孔道结构的配位聚合物:{[Ho(bta)(H2O)]?1.26H2O}n(1).X射线单晶衍射分析表明该配合物属三斜晶系,空间群P-1,晶胞参数a=0.7621(4)nm,b=0.9634(4)nm,c=1.0500(5)nm,α=106.409(18)°,β=105.273(18)°,γ=100.88(2)°,Z=2,V=0.6839(6)nm3,Dc=2.208g/cm3,μ=5.824mm-1,F(000)=437,R1=0.0224,wR2=0.0462.在1.8～300K的温度范围内研究了该配合物固体样品的磁性质.更多还原

【Abstract】 A holmium(III) coordination polymer {[Ho(bta)(H2O)]?1.26H2O}n (1), with a three-dimensional channel-like structure, was obtained by assembly of flexible tripodal ligand 1,3,5-benzenetriacetic acid (H3bta) with Ho(NO3)3?6H2O under hydrothermal conditions. The X-ray single crystal diffraction analysis reveals that the complex is triclinic with space group P-1, a=0.7621(4) nm, b=0.9634(4) nm, c=1.0500(5) nm, α=106.409(18)°, β=105.273(18)°, γ=100.88(2)°, Z=2, V=0.6839(6) nm3, Dc=2.208 g/cm3, μ=5.824 mm-1, F(000)=437, R1=0.0224, wR2=0.0462. The magnetic property of the solid samples was studied in the temperature range of 1.8～300 K.更多还原
