采用水热法合成了稀土配位聚合物{[Nd2(C2O4)3(H2O)6].3CH3OH}n(1),得到该配合物的粉红色块状晶体,并对其进行了元素分析。用单晶x射线衍射法测得其晶体结构,属单斜晶系,空间群为P21/c,晶胞参数为:a=1.1200(2)nm,b=0.96325(17)nm,c=1.02580(18)nm,α=90°,β=114.278(3)°,γ=90°,Z=4,V=1.0088(3)nm3。配合物中钕离子为九配位,与配体结合生成蜂窝状二维层,通过氢键的连接形成了三维超分子配合物。
The rare earth coordination polymer {[Nd2 (C2O4) 3 (H2O) 6] .3CH3OH} n (1) was synthesized by hydrothermal method, and the pink massive crystals of the complex were obtained. The crystal structure was determined by single crystal X-ray diffraction. It belongs to the monoclinic system with space group P21 / c. The unit cell parameters are: a = 1.1200 (2) nm, b = 0.96325 (17) nm, c = 1.02580 (18) nm, α = 90 °, β = 114.278 (3) °, γ = 90 °, Z = 4, V = 1.0088 (3) nm3. The neodymium ion in the complex is a nine-coordinated ligand, which combines with the ligand to form a honeycomb two-dimensional layer. The three-dimensional supramolecular complex is formed by hydrogen bonding.
