一例新颖钕(Ⅲ)配合物的合成及晶体结构

Synthesis and Crystal Structure of a Novel Nd(Ⅲ)-organic Framework Containing 5-triazole Isophthalic Acid

以5-取代的间苯二甲酸5-(4H-1,2,4-triazol-4-yl)isophthalicacid(H2L)、硝酸钕、DMF,水为起始原料,采用水热法合成了一例新颖的三维钕配合物[Nd4L6(H2O)4]·xsolvents(1),并通过单晶X-射线衍射技术测定了其晶体结构。测试结果表明:该配合物为三斜晶系,P-1空间群,晶胞参数a=12.855(3)A,b=13.841(3)A,c=24.421(5)A,α=86.16(1)°,β=76.429(11)°,γ=84.064(10)°,V=4197.1A3,Z=2。

A novel three-dimensional Nd(Ⅲ)-organic framework,[Nd4L6(H2O)4]·xsolvents(1)was synthesized under solvothermal conditions by using5-substituted isophthalic acid ligand 5-(4H-1,2,4-triazol-4-yl)isophthalic acid(H2L),Nd(NO3)3,DMF and water as raw materials.Single-crystal X-ray diffraction analysis revealed that the compound crystallizes in the triclinic,P-1 space group,with a=12.855(3)A,b=13.841(3)A,c=24.421(5)A,α=86.16(1)°,β=76.429(11)°,γ=84.064(10)°,V=4197.1?3,Z=2.
