摘要: Abstract Crystallographically characterized anti-[(μ-bmptz){fac-PtBrMe3}2], bmptz = 3,6-bis(2-(4-methylpyridyl))-1,2,4,5-tetrazine, could be reversibly reduced at −0.36 V vs. [FeCp2]+/∘ in CH2Cl2/0.1 M Bu4NPF6 to a persistent anion. Despite the presence of two conjugatively coupled platinum(IV) centers and bromide ligands as potential leaving groups it is bridging bmptz ligand which accepts added electron within tetrazine ring evident from EPR UV–Vis spectroelectrochemistry that diplatinum(IV) radical complex. The function methyl [fac-PtMe3]+ ions discussed contrast with related entity [fac-Re(CO)3]+.
