Abstract
The incorporation of transition metals into hybrid uranyl materials can result in more diverse structural topologies and variations in physical and chemical properties. To explore the impact of transition metals on the uranyl cation, five uranium containing bimetallic chain compounds, [(UO2)M(PDC)2(H2O)4]·4(H2O) (PDC = 2,6 pyridinedicarboxylate; M = Ni2+, Co2+, Fe2+, Zn2+, and Cu2+) were synthesized by evaporation of aqueous solutions at room temperature. The uranyl cation is complex by two PDC ligands and the transition metal cations bond to the complex to form a one-dimensional chain topology. The presence of the transition metal leads to the presence of a stronger uranyl oxo bonds as shown by the single-crystal X-ray diffraction data and the Raman spectra. Solid state diffuse reflectance UV/Visible spectra confirmed the presence of the transition metals in the structure by the broad bands that appeared at relevant wavelengths. Synthesis and characterization of [(UO2)M(2,6 pyridinedicarboxylate)(H2O)4]·4(H2O) [M = Ni2+, Co2+, Fe2+, Zn2+, and Cu2+] compounds reveals impact of transition metals in uranyl hybrid systems. [Display omitted] •5 heterometallic uranyl PDC compounds were synthesized and characterized by X-ray diffraction and spectroscopic techniques.•Uranyl PDC 1-D chain complexes that were linked via transition metal cations were further linked through π- πinteractions.•Structural data denotes shorter uranyl bonds in the presence of the transition metals and this is confirmed by Raman shifts.•Solid-state UV/Vis spectroscopy confirms the presence of transition metals in this system.
