Abstract
The manganese stannylidyne complex 41 appeared to be a suitable precursor to prepare an open-shell stannylidyne complex featuring a tin-centered unpaired electron. As expected for a Fischer-type tetrylidyne complex, quantum chemical calculations of 41 revealed that the LUMO+1 and LUMO corresponding to the \(\pi_{\text{in}}^{*}\) and \(\pi_{\text{out}}^{*}\) Mn–Sn bonds are mainly tin centered (vide supra). Auspiciously, the energy of the LUMO of 41 (−4.41 eV) is much lower than that observed for the isolobal group 6 metal tetrylidyne complexes.

The plot of the extinction versus concentration always showed a linear dependence with R2 ≥ 0.968 indicating that the Lambert-Beer law is obeyed in the range of concentrations employed.

In the Q-band spectrum, the third component of the g-tensor was not observed as it appeared outside of the measured spectral window.
