Abstract
Pyrrophen ligands are acyclic hexadentate ligands containing salen-type N donors: two phenolic O donors, two pyrrolic N-type donors, and two oxo-carbonyl coordinating units. Uranyl complex derivatives of pyrrophen UO2L1–2a-c (L1=H); (L2=CH3); (L=2-pyridinemethanol (a), N-(2-pyridinylmethyl) (b), N-benzyl (c), were synthesized and characterized by x-ray diffraction (XRD), nuclear magnetic resonance (NMR), and UV-vis. Each uranyl-containing structure was found to crystalize in a hexagonal bipyramidal coordination environment. We observed solid-state coordination deviations caused by the amide/ester substituent. The inductive effects and structural features were examined, and the effects on the bond lengths of the uranyl coordination and deviations in the -yl oxygen bond lengths and angles were studied.
吡咯烷配体是一种无环六价配体，含有沙仑型 N 给体：两个酚 O 给体、两个吡咯烷 N 型给体和两个氧代羰基配位单元。通过 X 射线衍射 (XRD)、核磁共振 (NMR) 和紫外可见光，合成并表征了吡咯烷 UO2L1-2a-c （L1=H）；（L2=CH3）；（L=2-吡啶甲醇 (a)、N-（2-吡啶甲基） (b)、N-苄基 (c)）的铀络合物衍生物。研究发现，每种含铀结构都能在六角双锥配位环境中结晶。我们观察到酰胺/酯取代基引起的固态配位偏差。我们考察了感应效应和结构特征，并研究了铀酰配位键长度的影响以及-基氧键长度和角度的偏差。
