摘要: |
从Ln-Ala-NA溶液(Ln=Nd,Ala=L-丙氨酸,NA=烟酸)中得到烟酸钕晶体,其晶体结构用四元X射线衍射技术测定。化合物为二聚体结构,属单斜晶系,P21/c空间群,晶胞参数:a=9.686(2)Å,b=11.9969(11)Å,c=17.2206(13)Å,U=92.550(9)°,V=1999.2(4)Å3,Z=2,Dc=1.816mg/m3。Nd配位数为8,配位多面体为畸变四方反棱柱。 |

Abstract: |
The complex crystal was obtained from the solution with Ln-Ala-NA(Ln=Neodymium, Ala=L Alanine,NA=Nicotinic acid), and the crystal structure has been determined by four-tetracyclic X-ray diffraction techniques.The compounds is dimer and crystallize in the monoclinic system space group P21/c with lattice parameters a=9.686(2)Å,b=11.9969(11)Å,c=17.2206(13)Å,U=92.550(9)°,V=1999.2(4)Å3,Z=2,Dc=1.816 mg/m3。The Nd ions have 8coordinated in a distorted tetragonal antiprism. |
