¹⁸⁷Os nuclear resonance scattering to explore hyperfine interactions and lattice dynamics for biological applications.

ABSTRACT: Osmium complexes with osmium in different oxidation states (II, III, IV, and VI) have been reported to exhibit antiproliferative activity in cancer cell lines. Herein, we demonstrate unexplored opportunities offered by ¹⁸⁷Os nuclear forward scattering (NFS) and nuclear inelastic scattering (NIS) of synchrotron radiation for characterization of hyperfine interactions and lattice dynamics in a benchmark Os(VI) complex, K₂[OsO₂(OH)₄]. We determined the isomer shift [δ = 3.3(1) millimeters per second] relative to [Os^IVCl₆]^2- and quadrupole splitting [ΔE_Q = 12.0(2) millimeters per second] with NFS. We estimated the Lamb-Mössbauer factor [0.80(4)], extracted the density of phonon states, and carried ou
