| 摘要: 二苄亚砜硝酸钕Nd(NO3)3·[(C6H5CH2)2SO]3属三斜晶系,P1空间群,晶胞参数:a=9.835(2),b=12.445(2),c=19.971(5)Å,α=104.13(2)°,β=90.34(2)°γ=74.96(1)°Z=2。晶体结构用重原子法解出,经最小二乘修正后R因子为0.031。钕离子由九个氧配位,形成稍歪扭的三帽三方棱柱配位多面体,其中一个三角面由三个二苄亚砜(DBSO)提供的氧形成,其他氧原子则由硝酸根提供。平均Nd-O(DBSO)=2.379Å,Nd-O(NO3)=2.536Å。 |

| Abstract: The title compound, Nd(NO3)3·[(C6H5CH2)2SO]3, crystallizes in triclinic space group P1 with unit cell parameters a= 9.835(2), b=12.445 (2), c= 19.971(5)A, α= 104.13(2)°,β= 90. 34(2)°,γ = 74.96(1)°and Z= 2. The structure was solved by heavy-atom method and refined by least-squares procedures to a final R 0.031. The neodymium is coordinated by nine oxygen atoms which form a slightly distorted tricapped trigonal prism. The oxygen atoms of three dibenzyl sulphoxide(DBSO) occupy a triangular face of the trigonal prism while the oxygen atoms from nitrate groups occupy the remaining sites. The average distance Nd-O(DBSO) is 2.379Å and Nd-O(NO3) 2.536Å. |
