硝酸铈(Ⅲ)与二缩三乙二醇-二-(8’-喹啉)醚(L)的配合物[Ce(C_(24)H_(25)N_2O_4)(NO_3)_4]晶体属三斜晶系,PT空间群;α=9.579(3),b=12.548(2),c=13.801(2)A,α=106.36(1),β=86.12(2),γ=112.43(2)°,V=1469.58A~3;Z=2,D_6=1.99g/cm~3;R=0.019。在配合物的分子中Ce~(3+)与L的一个喹啉N原子三个醚氧原子和四个双齿配位NO_3中的八个氧原子配位,铈的配位数为12。分子中有一个氢离子与另一个喹啉N原子结合并与硝酸根的氧原子形成氢键,从而使配合物分子在能量上得到补偿。
The complex [Ce (C_ (24) H_ (25) N_2O_4) (NO_3) _4] of cerium (III) nitrate and triethylene glycol-di- Α = 9.579 (3), b = 12.548 (2), c = 13.801 (2) A, α = 106.36 (1), β = 86.12 (2) and γ = 112.43 (2) °, V = 1469.58A~3; Z = 2, D_6 = 1.99g / cm~3; R = 0.019. In the complex, Ce ~ (3+) complexes with three oxygen atoms of one ether of a quinoline N atom in L and eight oxygen atoms in four bidentate NO_3. The coordination number of cerium is 12. One hydrogen ion in the molecule binds to another N atom of quinoline and forms a hydrogen bond with the oxygen atom of the nitrate, thereby allowing the complex molecules to be energetically compensated.
