合成了Ce[PO_2(OC_2H_5)_2]_3和Pr[PO_2(OC_2H_5)_2]_3(简称Ce(DEP)_3和Pr(Pr(DEP)_3)。用四圆衍射仪测定了其晶体结构。它们均属三斜晶系,空间群P1。晶胞参数,对Ce(DEP)_3:α=10.324(4)A,b=12.861(4)A,c=13.998(5)A,x=106.49(3)°,β=112.83(4)° γ=115.61(3)°,V=1296(1)A~3,Z=2;对Pr(DEP)_3:α=10.27(1)A,b=11.81(1)A,c=12.51(1)A,x=109.93(9)°,β=111.9(9)°,γ=93.0(1)°,V=1293(3)A~3,Z=2。用Patterson法并经分块全矩阵最小二乘法修正,最后的R值,Ce的为0.1071,Pr的为0.1066。结构分析指出,两种配合物结构类似,Ce和Pr原子均由二乙基磷酸根的六个氧原子配位形成八面体构型。
The crystal structures of Ce [PO_2 (OC_2H_5) _2] _3 and Pr [PO_2 (OC_2H_5) _2] _3 (Ce (DEP) _3 and Pr (DEP) _3) were synthesized and characterized by four- All belong to triclinic and space group P1. The unit cell parameters are Ce (DEP) _3: α = 10.324 (4) A, b = 12.861 (4) A, c = 13.998 (5) A, x = 106.49 3) °, β = 112.83 (4) ° γ = 115.61 (3) °, V = 1296 (1) A~3, Z = 2; for Pr (DEP) 11.81 (1) A, c = 12.51 (1) A, x = 109.93 (9) °, β = 111.9 (9) °, 2. Patterson method and the block full matrix least squares method to amend the final value of R, Ce is 0.1071, Pr is 0.1066. Structural analysis shows that the two complexes are similar in structure, Ce and Pr atoms by the second The six oxygen atoms of the phosphate group coordinate to octahedral configuration.
