Complexes of Uranyl Nitrate with 2,6‐Pyridinedicarboxamides: Synthesis, Crystal Structure, and DFT Study
Zeitschrift für anorganische und allgemeine Chemie(2017)
摘要
Two complexes of uranyl nitrate with N,N,N′,N′-tetrabutyl-2,6-pyridinedicarboxamide (TBuDPA) and N,N′-diethyl-N,N′-diphenyl-2,6-pyridinedicarboxamide (EtPhDPA) were synthesized and studied. The complex of tetraalkyl-2,6-pyridinedicarboxamide with metal nitrate was synthesized for the first time. XRD analysis revealed the different type of complexation: a 1:1 metal:ligand complex for EtPhDPA and complex with polymeric structure for TBuDPA. The quantum chemical calculations (DFT) confirm that both ligands form the most stable complexes that match the minimal values pre-organization energy of the ligands.
