合成了三(1—苯基—3—甲基—4—三氟乙酰基吡唑啉酮—5)二水合钕(Ⅲ)萃合物。经元素分析确定其组成为Nd(PMTFP)_3·2H_2O,X射线单晶衍射测定了化合物的晶体结构及分子结构。晶体属单斜晶系,P2_1/c空间群,晶体学参数如下:a=17.799(9)×10~(-10)m,b=12.661(6)×10~(-10)m,c=18.691(7)×10~(-10)m,β=102.71(6)~0,v=4108.8(10~(-10)m)~3,Z=4.分子中中心原子钕与八个氧原子成配位键,其中六个氧来自三个双齿配位的PMTFP-基,其余两个氧则由两个水分子所提供,八个氧原子取四方反棱柱型排列在钕的周围。
A neodymium (III) tris (3) complex of tris (1-phenyl-3-methyl-4-trifluoroacetylpyrazolone-5) dihydrate was synthesized. The crystal structure and molecular structure of the compound were determined by elemental analysis of Nd (PMTFP) _3 · 2H_2O and X-ray single crystal diffraction. The crystal belongs to the monoclinic space group P2_1 / c with the following crystallographic parameters: a = 17.799 (9) × 10 -10 m, b = 12.661 × 10 -10 m, c = 18.691 (7) × 10 ~ (-10) m, β = 102.71 (6) ~ 0, v = 4108.8 (10 ~ (-10) m) ~ 3 and Z = Atoms into coordination bonds, of which six oxygen from the three bidentate coordination of PMTFP-based, and the remaining two oxygen is provided by the two water molecules, eight oxygen atoms take square anti-prismatic arrangement around the neodymium.
