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.
A coordination polymer with three-dimensional pore structure was obtained by hydrothermal synthesis of a flexible tripod ligand, 1,3,5-benzenetricarboxylic acid (H3bta) and Ho (NO3) 3? 6H2O. (H2O)] 1.26H2O} n (1). X-ray single crystal diffraction analysis showed that the complex belongs to the triclinic system with space group P-1. The unit cell parameters are a = 0.7621 (4) nm and b = 0.9634 (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. The magnetic properties of solid samples were studied in the temperature range of 1.8 ~ 300K.
