Synchrotron based nuclear forward scattering (NFS) experiments using the 193Ir nucleus have been performed for the first time on a dinuclear iridium(I) complex, [IrCl(COD)]2 with COD being cycloocta-1,5-diene. This complex serves as a catalyst for hydrogenation and other chemical reactions. Both, the obtained absolute values of the isomer shift δ = 0.87 mm s - 1 and the quadrupole splitting Δ E Q = 3.82 mm s - 1 agree within the experimental error with values obtained via conventional 193Ir Mössbauer spectroscopy reported earlier (Gál M. et al. J. Radioanal. Nucl. Chem., 260 (1) 2004, 133). In addition, we present density functional theory (DFT) calculations of the complex yielding its electronic structure and related Mössbauer parameters.
