as potential leaving groups it is the bridging bmptz ligand which accepts the added electron within the tetrazine ring as evident from EPR and UV–Vis spectroelectrochemistry of that diplatinum(IV) radical complex. The function of the methyl groups in the [fac-PtMe3]+ ions is discussed in contrast with the related entity [fac-Re(CO)3]+.
