Synthesis and Characterization of Three-Dimensional Uranyl Coordination Polymers Containing Selenophene and Tellurophene Linkers

This work was supported by the University of Iowa (UI), Office of the Provost, High Impact Hiring Initiative, and by start-up funds from the UI College of Liberal Arts and Sciences and the Department of Chemistry. EC would also like to thank the University of Iowa Graduate College for a Spring 2025 Post-Comprehensive Exam Graduate Research Fellowship. We acknowledge the University of Iowa Materials, Analysis, Testing, and Fabrication Facility which houses the single-crystal X-ray diffractometer, powder X-ray diffractometer, Raman microscope, thermogravimetric analyzer, and scanning electron microscopes used in this study. We would specifically like to thank MATFab staff member Dr. Daniel K. Unruh for support and guidance associated with SC-XRD data refinements. Single-crystal XRD data were collected on an instrument funded by NSF Award CHE-1828117. Field emission SEM/EDS data were collected on an instrument funded by NSF Award EAR-2215495. The NMR instruments used to confirm ligand formation and purity were supported by funding from the University of Iowa. Mid- and far-IR spectra were collected on an instrument funded by a Nuclear Regulatory Commission Faculty Development Grant (NRC 31310018M0042). A preprint reflecting a preliminary version of the findings reported here was posted to a preprint server.
