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＝2.208 g/cm3, μ＝5.824 mm－1, F(000)＝437, R1＝0.0224, wR2＝0.0462. 在1.8～300 K的温度范围内研究了该配合物固体样品的磁性质.

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.
